Acceler-8 I-90 Bridge: Cordaville Rd to be closed (4pm Friday through early Monday)

Above: Last weekend, construction crews installed a new MassPike bridge span over Woodland Road. This weekend, they’ll continue the Acceler-8 project, working on the Cordaville Road bridge. (images cropped from photo tweeted by Mark McGrath @ConstBoss and project flyer)

This weekend, MassDOT will replace the second of the eight MassPike bridge spans being replaced this summer in/near Southborough. This time, they’ll be working on Cordaville Road.

In addition to impacting MassPike travelers, this weekend’s work will temporarily close Cordaville Road to through traffic. Scroll down for the details.

Last weekend, the state crew replaced the westbound span of the Woodland Road bridge. Throughout the weekend, @MassDOT tweeted pics and videos of the work in progress. 

Below is a video of a pre-constructed bridge section being lowered into place by a crane:

I-90 West Bridge Replacement over Cordaville Road in Southborough, June 25 – 28

I-90 West Traffic Shifted to I-90 East, Travel Reduced to Two Lanes in Each Direction

Cordaville Road Closed to Through Travel, Detours in Place

What is happening

MassDOT is replacing bridges on I-90 east and westbound over Flanders Road in Westborough and Parkerville Road, Cordaville Road, and Woodland Road in Southborough as part of this project. The replacement of the eight bridges (2 spans per local road) will take place over eight weekends between June 18 and August 16, 2021.

I-90 West bridge over Cordaville Road replacement

MassDOT will replace the I-90 West bridge over Cordaville Road in Southborough from 7:00 PM on Friday, June 25 to 5:00 AM on Monday, June 28. Westbound traffic will be shifted through a median crossover to the eastbound side of I-90. Travel will be reduced to two lanes in each direction and opposing traffic separated by a barrier.

Cordaville Road will be closed under the bridge and through traffic detoured from approximately 4:00 PM on Friday to 5:00 AM on Monday.

There will be advance signage in place to alert drivers to the I-90 configuration change and Cordaville Road detour.

Schedule (weather dependent)

Note: All times are subject to change based on weather or unforeseen events.

Friday Night, June 25 (beginning at 7:00 PM):

  • I-90 westbound (WB) traffic will be shifted through the median crossover into two right lanes of what is usually I-90 eastbound (EB)
  • I-90 EB traffic will be shifted to the right into two lanes

Monday Morning, June 28 (completed at 5:00 AM):

  • I-90 WB traffic will be shifted back to three lanes on I-90 WB
  • I-90 EB traffic will be shifted back to three lanes on I-90 EB

Alternate timeframe (should weather cause impacts)

If there is inclement weather that impacts the schedule above, MassDOT will reschedule the replacement to the weekend of July 9 – 12.

How will this affect me?

If you travel on I-90:

During the replacement, both directions of I-90 will be reduced from three to two lanes between Route 9 in Framingham (Exit 111) and I-495 (Exit 106) in Hopkinton, which will result in higher than normal congestion.

If you use Cordaville Road:

Cordaville Road will be closed to through travel. Local access to homes and businesses will be maintained on either side of the bridge. The detour route map can be viewed on the website.

Travel Tips

Plan ahead: The reduction of I-90 from three to two lanes will result in higher than normal congestion, drivers should plan accordingly.

Drivers traveling WB through the project should be prepared for the shift into the EB direction.
