I-90: Pennsylvania Avenue Bridges

The 1960 structures over Pennsylvania Avenue on I-90 in CDA will be replaced in 2020.

Replacement is estimated to take until October, with a complete closure of the road and sidewalks underneath to ensure safety and efficiency. Demolition and pile-driving activities are expected to create noise and vibration impacts, though that kind of work will be limited to daytime hours.
