The drawbridge at Granite Avenue near Exit 11B will be closed for the weekend from Fri., Oct. 23 through Mon., Oct. 26 as workers replace a steel beam on the span over the Neponset River. The emergency project will result in detours and the closure of expressway on-and-off-ramps at exit 11.
The area will be closed off to all traffic at 8 p.m. on Oct. 23. "All lanes will be open to traffic by Monday, October 26 at 5:00 a.m.," a statement from the Massachusetts Department of Transportation (MassDOT) said on Wednesday.
Digital signboards on roadways near the bridge warned motorists of the impending plan this week. The bridge was last closed for repairs in August 2018, causing overnight detours and necessitating the closure of the expressway off-ramp as well. At that time, a MassDOT spokesperson said crews were “carrying out minor structural repairs and doing steelwork on the moveable span of the bridge.”
