This page provides monthly updates of work completed over the course of the 16-month construction phase of the project, culminating with the laying of the final concrete panel in September, 2009. A few short weeks later the new Walkway Over the Hudson State Historic Park opened to the public! We have included a rich variety of photos chronicling the successful effort to transform the Poughkeepsie-Highland Railroad Bridge into the Walkway Over the Hudson State Historic Park.

The work is essentially done. The construction team is finalizing all of the details in preparation for the Grand Opening October 2nd and 3rd.
The concrete panels are all installed and the railings are 100% completed. The approaches are paved and ready to be striped for parking. The west monumental gate has been installed and the east gate will be done shortly.
Final work installing kiosks, banner poles and banners, the last of the safety fencing, expansion joints, seam caulking and bridge cleaning is scheduled for the next few days.
Future work after the opening will include deck lighting and power outlets as well as security system enhancements all by November and a grand elevator up to the Walkway at the Poughkeepsie river front by Fall of next year.

Work remains on schedule for the October 3 rd Grand Opening despite some very rainy weather in June and early July, which put a big dent in our contingency time.Manufacture of the concrete panels is 100% complete. They are stored at the Fort Miller Company in Schuylerville, New York and moved to the site as needed for installation.
Metal repairs are 91% completed as of the end of July. Some last minute joint replacements were made after the inspection after rust removal indicated more section loss than previous measurements. One repair is very difficult since it is located over the Metro North railroad tracks and work must be coordinated with train schedules.
Panel installation stands at 84%. The install rate is limited by the the metal repair work. The crane to install panels can not be moved until the metal repairs are completed in order to insure the bridge has enough strength to support the load of the crane.
Railing installation is at a little over 80%. It closely follows the panel installation. Caulking of the seams is closely following the railing installation.
The construction team has created a punch list of final work items including approach grading and paving, gate installation, major expansion joint installation and a large number of finishing items.
The bids for the electrical and security work on the bridge were received and a contract will be awarded shortly. This work is scheduled for completion in November, and will not hamper the opening of the bridge in October.

Overall we are still comfortably on schedule for the Grand Opening the first weekend in October.
Steady progress was made on the bridge work in May. Panel installation is now at about 65%, and metal repairs are at about 60%. Metal repairs must be completed before the large crane used to place the panels can be moved into place. The progress of metal repairs will limit panel and railing installation from now until the end of the project. There is a metal repair team on each side of the river. Their progress is being tracked on a daily basis. They should meet each other at a point close to the eastern shore of the river in early August.
Work installing railings is also right behind the panel installation at over 57%.
The caulking of seams between the panels is in the 20% range. It is being accomplished when ever other work does not cause traffic interference problems.
Fort Miller Company in Schuylerville, New York has completed the manufacture of 98% of the panels. They are stored in their yard and delivered as needed to the site for installation.
We are comfortably on schedule for the Grand Opening the first weekend in October.
With great cooperation from the weather, over 50% of the new deck panels have now been installed on the bridge.
On the east end panel installation has proceeded from Washington Street almost to Route 9. On the West side panels have been installed out through the first observation area over the water. Scaffolding has been installed on pier #3 and metal repairs are underway on the pier as well as the structure between piers 3 and 4.
Railings are currently being installed on the east side of the bridge and the seams between panels are being filled with an elastic material.
At Fort Miller Company, near Saratoga, New York, over 85% of the concrete panels have now been produced. It is likely that by the end of May they will all be done and ready to be installed.
With the arrival of warmer weather, the Harrison & Burrows team has resumed the placement of concrete panels. In addition to picking up where they left off on the west end of the bridge — with panels just begin to extend out over the water — the team has also begun laying panels on the east end of the bridge, where it meets land in Poughkeepsie. The photos below are of the first concrete panels being put down on the east end.
As of the end of January the project remains on schedule for completion in September 2009.
Our architect and engineering team at Bergmann Associates continue to respond to daily problems and minor changes. The details of each metal repair often require "on the fly" modifications to reflect actual conditions revealed when an individual repair begins.
Our railing manufacturer continues to produce and stockpile railings for the bridge.
A detailed planning session for all remaining work was held in early January confirming all of the work schedules for the project. There will be over 50 people working on the bridge once the weather breaks in the Spring.
We are happy to report that, as of the end of November, the project remains on schedule for completion in September 2009.
November was a busy month. The crane supporting metal structural repairs is now visible out over the river on the western shore. Work on metal structural repairs will continue through the winter, moving from the west shore towards the eastern shore. In addition, at the end of this month a second metal repair crew started at the Washington Street abutment and is moving to the west. They are working off of lifts from the ground. This work will also continue throughout the winter.
Panel placement on the west approach has been completed and the initial panels for the main span on the west shore have been placed. Panel placement will be suspended for the winter due to the fact that cementing the panels to the metal structure requires the temperature to be above freezing so that the grout will cure properly.
New galvanized steel railings have been installed on both sides of the west approach. With the exception of sealing all of the joints between panels and other minor work, the west approach is virtually completed.
The Fort Miller Company continues to manufacture panels for the main span and the east approach in their heated factory near Schuylerville in upstate New York. The work will continue all winter, and when panel placement resumes in the spring they will have over 75% of the panels ready to install.
Project safety remains a major focus. In November a new safety cable stretching from the new panels on the west approach all the way across the river to the Washington Street abutment was installed. Iron workers on the bridge are always attached to the cable when working or moving across the structure. Weather conditions are analyzed each day before starting work to make sure that the work planned for the day can be done safely.
Walkway construction remains on schedule for completion by September 2009.
The Fort Miller Company completed all 151 concrete panels needed for the west approach portion of the bridge. They continue to make identical panels for the east approach to the bridge which will be installed starting in the spring.
Fort Miller is also now manufacturing concrete panels for the main section of the bridge. These panels are custom manufactured to match the exact distance between the floor beams on the bridge. Production at Fort Miller will continue throughout the winter to create a stockpile of material ready to be installed in the spring.
Harrison and Burrowes has continued panel installation this month completing the 151 panels on the west approach. They will shortly move on to install panels on the main portion of the bridge as long as weather permits. The crane that supports the panel installation can be seen from the wast side of the river emerging from the trees. H&B also continues to do structure repairs on the main span and have recently started doing structure repairs on the east approach to the bridge. Structure repair work will continue throughout the winter with a short break mid December to mid January.
On October 29th a Harrison and Burrowes subcontractor began the installation of the permanent railings on the west approach. This work is being done earlier than scheduled and will provide an improvement in the safety of moving construction materials and people out to the work location over the river. The west approach railing work should be completed in about two weeks, allowing main span panel installation to resume.
The goal of the construction team is to have some experience with all of the different types of work this fall so that accurate plans can be made to complete the project. The last major activity not yet started is installation of main span panels. This work is scheduled to start mid November and continue as long as weather allows.
Walkway construction remains on schedule.
The Fort Miller Company has produced 140 panels of the 151 needed for the west approach portion of the bridge. They continue to produce 3 panels a day. Shop drawings detailing the main span panels over the water have been approved and molds for forming the panels are being built. The length required for each panel is being uniquely measured on the bridge super structure and the panels are being custom built to the actual dimensions of the bridge. Main span panel production is now scheduled for the second week in October.
Harrison and Burrowes, the contractor doing the work at the site, has installed 64 panels representing over 380 feet in length. Installing the panels involves welding six vertical posts on the girders of the bridge. The panel is then placed over the posts and carefully leveled and aligned with leveling screws. When it is in proper position the space between the panels and the bridge and the opening around the posts is filled with grout. Grout is a special type of highly liquid fast setting cement. Within a few hours the panels are ready for bearing the load of placing the next set of panels. As the panels are installed every third railing post is installed, metal cable is stretched between the posts and temporary orange fencing is attached to the railing posts and cables for safety purposes. By the end of the month bright orange fencing will be emerging from the trees on the west bank of the river and will mark construction progress for the rest of the project.
Harrison and Burrowes has also begun the metal and foundation repairs on the bridge. As of the end of September 15th of the steel repairs have been completed. These repairs must be done before panels are installed so that the bridge will have the extra weight carrying capacity needed to support the weight of the 110 foot crane used to lift and place the panels.
The engineering team from Bergmann associates continues to respond daily and visit at least weekly to address any issues that arise as the bridge rehabilitation continues. Their fast response has a major influence on maintaining the installation and repair schedule.
Safety remains a major focus for the project. Anyone working within six feet of the edge of the bridge must be attached to the structure with a harness and lifeline. Selected workers with climbing skills are identified as emergency responders in case of a problem. Even minor incidents are reported to the full-time safety officer on the site and are logged with corrective action noted. Safety practices specific to the days activity are part of the daily briefing before work begins. After hours the site is secured with temporary fencing backed up by lights, recording security cameras and motion detectors tied into the local police.
Walkway construction remains on schedule through August 31, 2008.
Environmental Remediation Services has completed all of the demolition work scheduled for this fall. In the spring or early summer of next year they will complete removal of the old power lines, using the new deck structure to access them.
Fort Miller Company has produced 87 panels of the 151 needed for the west approach portion of the bridge. They continue to produce three panels a day. Shop drawings detailing the main span panels have been almost entirely released and forms for casting the panels are in the process of being built. Panel production for main span panels will begin before the end of September.
Harrison and Burrowes, the contractor doing the work at the site, has mobilized for the work. They graded a construction yard at the west end of the bridge, brought in and assembled the main crane for placing the panels, and placed multiple construction trailers. They have prepared a detailed safety plan governing all aspects of work on the site.
Harrison and Burrowes has also begun the metal and foundation repairs on the bridge. These repairs must be done before panels are installed so that the bridge will have the extra weight carrying capacity needed to support the weight of the crane.
Walkway construction work remains on schedule through July 31, 2008.
The removal of the old railroad ties, metal railings, water pipe and walking surfaces is approximatley 75% complete. A decision has been made to delay removal of the old power lines attached to the bridge until the new deck is in place. With the new deck on the bridge a large boom truck will make the wire and trestle structure removal much easier. It is anticipated the Environmental Remediation Services, Inc. will complete their work, except for the power line removal, by mid-August.
Harrison and Burrowes located in Glendale, New York, just south of Albany, was selected as the general contractor. Their responsibility will be the structural repairs, installation of the new deck panels and installation of the new bridge railings. They have begun their mobilization work in preparation for an August 15th start. The first activity will be structural repairs. A tool storage trailer and an office trailer to support their work have been placed on the land at the west end of the bridge. Their safety plan has been submitted for review by our construction manager.
The Fort Miller Company was selected to manufacture the concrete panels for the main span and east approach in addition to the panels for the west approach previously contracted with them. Sample panels were successfully manufactured and the results were reviewed during July. Manufacturing is underway for the concrete panels which will form the new deck. To date 48 panels have been produced and stored at the Fort Miller site near Saratoga, New York.
Work continued in earnest during the month of June to remove the old railroad ties and rail posts. As shown in the pictures below, equipment has been moved out onto the bridge and workers have begun to dismantle and remove some of the railings that line the main span.
May was a particularly exciting month for the Walkway project and its board, volunteers and supporters. Most of our internal efforts surrounded preparation for the ceremonial groundbreaking event, held on May 27. The day was a resounding success including excellent speeches from some of the Walkway's most prominent supporters as well as the announcement of Scenic Hudson's $1 million donation.
Immediately following the groundbreaking ceremony, the prep work for demolition began. The demolition plan has been submitted to the appropriate regulatory groups for approval. Simultaneously, initial work continued, focusing on preparing the western approach to the bridge for the arrival of larger machinery and material. The contractor has prepared a new road into the site to allow heavier trucks to enter. Additionally, the Fort Miller Company has completed the design for the concrete panels that will become the deck of the Walkway, and casting will begin within the next few days. The bidding for general construction is underway and we expect to complete the process by the end of June.
The New York State Office of Parks, Recreation & Historic Preservation, as lead agency, issued a negative declaration as part of the State Environmental Quality Review procedures. The "negative declaration" determined that the project will not have a significant effect on the environment. Demolition contract bids were opened and ERSI, Inc., of Schenectady, NY was the low bidder and was awarded the contract. Work is scheduled to begin shortly after Memorial Day. Work will include removing the remaining timber decking, railroad ties, utilities, and maintenance pedestrian railing.
Bergmann Associates, continued with multi-faceted project coordination including the preparation and awarding of the demolition and general contract bid documents, acquisition of permits and coordination with municipalities, construction inspection, and other tasks.
In March, 2008 an agreement was executed with the Fort Miller Company, Inc. to manufacture the precast concrete panels for the west approach spans of the bridge in the Town of Lloyd. The west approach is approximately 1,000 feet long. This proactive action to start manufacturing panels before the general contractor is selected, will help assure that the bridge is completed in time for the Quadricentennial Celebration in October 2009. In addition, a mandatory pre-bid meeting was conducted for contractors interested in the demolition and general contracts. Attendance was excellent, with 55 construction company representatives attending the meeting and site visit.

The Final Design Report, issued by Bergmann Associates, the engineering consulting firm overseeing the project, was issued in February 2008. The report addressed engineering, environmental, planning, and economic issues. The extensive report reflected the input of numerous state and local agencies, as well as the comments received from the 500+ people attending the January public information meeting.
