101 College Street Celebrates a Construction Milestone!

On Wednesday, October 12, the final steel beam was placed at the top of 101 College Street, and with that the building’s framing is complete! Over 43,000 tons of steel have been installed since construction of the new research and lab facility began in June, 2021. The occasion was celebrated with a “Topping Off Ceremony.”

Congratulations to the project team--especially Dimeo Construction, the contractors, and the construction workforce! Built on land made available for use by Downtown Crossing infrastructure work, 101 College Street will boost New Haven’s growing bioscience economy when it opens in mid-2023.

Thanks to New Haven residents and commuters for helping to keep the construction workers safe by driving with care near the construction zone. 

Traffic Alert: Inbound Lane Closures

Double and triple lane closures are occurring along the exit ramps that lead into Downtown New Haven from I-91 South and I-95 South.

This will impact drivers who take Exit 1 on I-91 South and drivers who take Exit 47 on I-95 South to enter the City, potentially causing backups especially during the morning rush hour.

While this work is not associated with Downtown Crossing, it is occurring in our project area and we wanted to alert drivers. 

This emergency bridge repair work is being performed by the Connecticut Department of Transportation (CTDOT) and is expected to last a few more weeks. We will keep you informed as we receive more information. 

Please pay attention to road signage, slow down, and stay safe!
