The Interstate 93 ramps to Granite Avenue in Dorchester are shut down due to a stuck drawbridge.
Massachusetts State Police say the northbound and southbound ramps of Interstate 93 in the Dorchester neighborhood of Boston are closed until further notice.
The drawbridge crossing the Neponset River is stuck open. Police say motorists should expect heavy delays in the area and seek alternative routes. No further information is available about why the bridge is stuck.
The 187-foot-long bridge, built in 1959, was closed for repairs in late April. A 2015 structural evaluation of the bridge found it to be in high priority of replacement.
