What's New

MassDOT will perform overnight emergency repairs to patch holes in the northbound deck of the I-91 Viaduct in Springfield between State Street and the I-291 interchange. This work will begin at 9:00 PM on Thursday, July 2. Two lanes will be closed on I-91 northbound beginning at 10:00 PM on Thursday, July 2 and will reopen at 5:00 AM on Friday, July 3. One lane of traffic will be maintained at all times. Those traveling through the area should expect delays and should reduce speed and use caution.

MassDOT's contractor, the Joint Venture of White-Schiavone, will begin construction work in early July. This first phase work will include utility work, intersection improvements and bridge deck repairs with nightly lane restrictions. The long-term viaduct lane closures are expected to begin this fall.

Traffic Management

Construction will take place in two phases requiring traffic shifts. Generally, the number of travel lanes on the viaduct will be reduced by one in each direction due to ramp closures.

Regional traffic will be maintained on the existing bridge and local traffic will be maintained on the surrounding city streets, including East and West Columbus Avenues. Traffic will be managed during the deck replacement through a combination of lane closures and shifts to establish work zones on the interior and then exterior of the northbound and southbound viaduct to complete the work.

In addition to the lane reduction on the viaduct, ramp closures will be needed through the work area. Exits 6 and 7 on I-91 southbound will be closed and traffic detoured to a temporary ramp to be constructed north of Exit 8 to provide access to downtown Springfield via West and East Columbus Avenues. The on-ramps to I-91 northbound from both State and Union Streets will also need to be closed. I-91 northbound access will be provided via East Columbus Avenue, with I-291 access provided via a detour off of East Columbus Avenue to Liberty and Dwight Streets.

About The Project

The Massachusetts Department of Transportation (MassDOT) is undertaking the Interstate 91 Viaduct Rehabilitation Project to replace the existing deck of the bridge, which is in poor condition. The project is the result of several years of planning and valuable input from a wide variety of stakeholders. The project has been designed to reduce the number of traffic stages and keep construction duration to a minimum. Once completed, the I-91 viaduct rehabilitation project will reduce annual maintenance costs, increase safety and accessibility on this busy interstate, and ensure long-term serviceability.

The southern limit of the project includes I-91 northbound and southbound, just south of State Street. The northern limit of the work is in the vicinity of the I-291 interchange ramps. Rehabilitation of the various on- and off-ramps between these limits and the I-291 ramp structures is included in this project. For more details, see the Deck Replacement Details Map

The completed bridge cross-section will be similar to the existing bridge width, with a wider left shoulder, three travel lanes and a wider right shoulder. During construction, there will be one travel lane north of the I-291 ramps, while two lanes will be maintained on the viaduct in each direction, with occasional exceptions possible. In addition to the bridge and highway improvements within the limits of the viaduct, MassDOT is proposing bridge drainage system enhancements that will improve water quality in the Connecticut River. Other improvements will include new lighting on the viaduct, the upper levels of the north and south garage, and the Columbus Avenue railroad underpass.

Upcoming Meetings/Projected Schedule

MassDOT hosted a construction kickoff public hearing on June 25, 2015, and several meetings during the design phase. Future quarterly update meetings will be announced on this website.

You can read the results of a recent online survey on travel and traffic patterns, which will help MassDOT assess potential detours and improvements.

Background

The elevated viaduct carries Interstate 91 (I-91) through Springfield, with the Interstate 291 (I-291) Interchange to the north and State Street to the south. I-91 has an Average Daily Traffic volume of approximately 75,000 vehicles per day, with 90,000 vehicles using the I-91/291 Interchange. The viaduct is the primary north-south route between Connecticut, Massachusetts and Vermont, and it experiences extensive vacation traffic during the weekends in the summer and winter.

The existing viaduct was built in the late 1960s and generally consists of a concrete deck slab supported on steel girders. The girders are supported by steel pier caps, column piers, and footings with pile foundations. Several rehabilitation projects were performed on the structures over the past 25 years; however, in recent inspections, MassDOT found that the bridge deck needs to be replaced.

Construction

The project involves replacing the concrete bridge deck with full depth concrete deck panels, painting of all structural steel, replacement of the bridge bearings, improvement of the bridge drainage and highway lighting, miscellaneous structural steel repairs, improvement to the traffic signage on the structure and various other safety improvements in the immediate vicinity of the bridge.
