Interstate 91 Viaduct Rehabilitation Project


Overnight Closures of I-91 South (at Exit 7) and Birnie Ave On-Ramp to I-91 South, April 11

MassDOT will close I-91 South at Exit 7 from 9:00 PM on Wednesday, April 11, to 5:00 AM on Thursday, April 12. The I-91 Southbound on-ramp from Birnie Avenue will also be closed during this timeframe, as it leads to the closed portion of the highway. These closures are necessary to allow the contractor to safely and effectively conduct construction operations.

The I-91 Southbound on-ramp from Hall of Fame Avenue (at Union Street) is also closed due to an adjacent project.

Signs will be in place indicating the following detour routes.

During the I-91 South and Birnie Avenue On-Ramp Closure:

  • To continue to I-91 South: Take Exit 7 (to Downtown Springfield) for West Columbus Avenue/Memorial Bridge. Continue on West Columbus Avenue/Hall of Fame Avenue for approximately 1.5 miles to the I-91 South on-ramp prior to the South End Bridge.
  • To access I-91 South from West Columbus Avenue/Birnie Avenue: Merge onto West Columbus Avenue and continue south onto East Columbus Avenue through the rail underpass. Bear right onto West Columbus Avenue behind the I-91 North Garage. Continue onto Hall of Fame Avenue and take the I-91 South on-ramp prior to the South End Bridge.
  • For downtown destinations: Take Exit 7 (to Downtown Springfield) and merge onto West Columbus Avenue. Continue to destinations in the downtown area.

MassDOT advises drivers to plan for additional travel time through this area. Those traveling through the area should follow the reduced speed limits and use caution.

Intermittent Single Lane Closures on East and West Columbus Avenue

Through September 2018, MassDOT will implement intermittent single lane closures on East and West Columbus Avenue between State Street and Clinton Street. The closures may occur between 7:00 AM and 3:00 PM, and occasionally overnight between 7:00 PM and 5:00 AM. They are necessary for bridge drainage installation, painting, and barrier work. No detour routes are required.

I-91 Lane and Ramps Reopened Ahead of Schedule

MassDOT reopened the following lane and ramps ahead of schedule in November and December 2017:

  • Birnie Avenue Connector on-ramp to West Columbus Avenue
  • Exit 6 off-ramp from I-91 South (to Union Street)
  • Union Street on-ramp to I-91 North
  • Exit 7 off-ramp from I-91 South (to Hall of Fame Ave/Downtown Springfield)
  • West Columbus Avenue on-ramp to I-91 South
  • Additional Lane on I-91 South
  • Additional Lane on I-91 North
  • State Street on-ramp to I-91 North

These ramps were closed in December 2015 for safety and operational reasons, and to expedite construction. They were originally scheduled to reopen in Spring 2018.

MassDOT permanently closed Temporary Exit 7-6 from I-91 South in November 2017. This temporary exit was opened in December 2015 to provide access during Stages 1 and 2 of construction.

The 40 miles per hour (MPH) reduced speed limit in the construction zone (and 45 MPH limit approaching the zone) will continue to be enforced by State Police monitoring the area and fines are doubled. These limits will be in place for the duration of the project. View a map showing where the reduced speed limits are in effect.

Other Restrictions

During construction, the north entrance to the North Parking Garage below the Viaduct is closed. The north exit remains open, but only right turns are permitted out of the garage, providing access onto East Columbus Avenue.

Traffic Mitigation

MassDOT has undertaken significant planning to improve traffic flow during the ramp and lane closures. Working with the City of Springfield, MassDOT developed detour plans and local improvements, as well as a comprehensive monitoring program of key corridors and intersections. Signs direct drivers to many Springfield destinations. The traffic plan is constantly updated based on ongoing monitoring. In addition, traffic mitigation includes:

  • Police details at critical intersections during peak periods
  • Monitoring cameras tied into the City of Springfield's system
  • Real Time Traffic Management System signage, known as RTTM
  • Incident Response Operations in case of a breakdown on the viaduct
  • Aid provided to emergency responders for efficient responses
