MassDOT will replace the I-90 East bridge over Cordaville Road in Southborough from 7:00 PM on Friday, July 30 to 5:00 AM on Monday, August 2. Eastbound traffic will be shifted through a median crossover to the westbound 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, July 30 (beginning at 7:00 PM):

I-90 eastbound (EB) traffic will be shifted through the median crossover into two right lanes of what is usually I-90 westbound (WB)
I-90 WB traffic will be shifted to the right into two lanes
Monday Morning, August 2 (completed at 5:00 AM):

I-90 EB traffic will be shifted back to three lanes on I-90 EB
I-90 WB traffic will be shifted back to three lanes on I-90 WB
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 August 6-9.

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 in Hopkinton (Exit 106), which will result in higher than normal congestion.

If you travel on I-495:

During the replacement, there will be higher than normal congestion along the I-495 corridor approaching the on-ramps to I-90.

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 bridges. The detour route map can be viewed on the website.

About the project
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) is taking place over eight weekends between June 18 and August 16, 2021.

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 EB through the project should be prepared for the shift into the WB lanes.
