Work is underway to remove the bridge over Water Street in New Haven and that will lead to road closures and detours over the weekend.
Officials from the state Department of Transportation said it has to come down because it's not in use, so from 9 a.m. on Friday to 6 p.m. on Saturday, the Trumbull Street onramp to Interstate 91 south will be closed, and drivers will be sent to State Street and north to the Willow Street entrance of I-91 South.
From 9 p.m. on Friday through 6 p.m. on Saturday, the right lane of I-91 South will be closed between the exit 4 off-ramp to State Street and the off-ramp to I-95. The I-91 South off-ramp to Route 34 West will also be closed.
The bridge removal work will also be local road closures.
Local streets will also be shut down, including Water Street, which will be closed between Brewery and East streets from 9 p.m. on Friday through 6 p.m. on Saturday.
Franklin Street will be closed between Chestnut and Water streets, with no through-traffic to Water Street for the same time span.
The right lane of I-91 south will also be closed between exit 4 and the off-ramp to I-95 southbound from 9 p.m. on Friday to 6 a.m. on Monday.
