Overnight Closure of Exit 8 from I-91 North to I-291 East and I-91 North Lane Closure

MassDOT will implement the following overnight closures on Thursday, December 1, and Friday, December 2, from 9:00 PM each night to 5:00 AM the following morning. This work will allow the contractor to set the new barrier for Stage 2.

  • Exit 8 from I-91 North to I-291 East/Route 20 East
  • Right lane on I-91 North throughout the work zone

Traffic will be routed to the following signed detour route:

  • To reach I-291 East/Route 20 East from I-91 North: Take Exit 10 for Main Street/Route 116. Take a right onto Main Street/Route 116. Turn left onto Liberty Street, then turn left onto Chestnut Street. Take the ramp on the right to access I-291 East/Route 20 East.

MassDOT advises drivers to plan for additional travel time through this area.

Intermittent Single Lane Closures on East and West Columbus Avenue - through December

Throughout the month of December, MassDOT will implement intermittent single lane closures on East and West Columbus Avenue between Hampden 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 so the contractor can install shielding and for demolition work. No detour routes are required.

Dynamic Lane Merge System Pilot Program

Beginning in late December 2016, MassDOT will implement a pilot program for a Dynamic Lane Merge System in the work zone on I-91 South. MassDOT will install traffic sensors and portable, changeable message signs in advance of ongoing lane closures (see below). The signs will provide instructions to drivers on lane use based on the existing traffic volume and speeds. When traffic is low and travel speeds are high, drivers will be advised to merge early. To reduce congestion during high traffic volumes while drivers are traveling at lower speeds, drivers will be instructed to remain in their respective lanes and take turns merging where the lane ends. The system is intended to enhance safety and improve traffic flow in the work zone.

I-91 Long-Term Lane Reductions, Ramp Closures and Detour Routes Continue through Spring 2018

During Stage 2, I-91 traffic is using the center, newly reconstructed lanes on the viaduct. Traffic on I-91 North shifted in November and traffic on I-91 South will shift in mid-December. Construction is now taking place on the low-speed travel lane and shoulder portions of the viaduct, along with the I-91 northbound on-ramp to I-291 East.

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.

Long-Term Ramp Closures

The following ramp was closed for Stage 2 on November 27, 2016 and will remain closed through spring 2018:

  • Exit 9 off-ramp from I-91 North to Route 20 West/Route 20A East to West Springfield/Westfield

The following ramps were closed on December 20, 2015 for safety and operational reasons, and to expedite construction. They will remain closed through spring 2018:

  • Birnie Avenue connector (closed since October 2015)
  • Union Street on-ramp to I-91 North
  • State Street on-ramp to I-91 North
  • Exit 7 (Hall of Fame Avenue / Downtown Springfield) off-ramp from I-91 South
  • Exit 6 (Union Street) off-ramp from I-91 South
  • Route 20 connector to I-91 South

MassDOT closed the Birnie Avenue Connector and has built a new West Columbus Avenue/Birnie Avenue off-ramp (temporary Exit 7-6) for I-91 southbound traffic to access downtown Springfield, the Memorial Bridge, and the Basketball Hall of Fame area.

Take Temporary Exit 7-6 to Access Greater Springfield

MassDOT encourages drivers to use Temporary Exit 7-6 for easier access to West Columbus Avenue and the greater Springfield area destinations previously served by the closed exit ramps, including Boland Way/Downtown, the Springfield Parking Authority I-91 Garages, the Memorial Bridge, and the Basketball Hall of Fame area. After the I-391 merge at the Chicopee Curve, keep right. The right lane on I-91 South connects traffic to Temporary Exit 7-6. The second from the right lane provides access to I-291 East/Exit 8. For more information, view the I-91 southbound lanes diagram.

Vehicular Width Restrictions on I-91 and I-291 in Springfield

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
  • Highway advisory radio
