​Overnight Closure and Detour Required for Concrete Deck Pour 

(September 7, 2022) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will perform a one-night closure and detour at the US 1 (Washington Boulevard) bridge over the CSX Transportation railroad lines in the Halethorpe area of Baltimore County from 9 p.m. Sunday, September 11, to 5 a.m. Monday, September 12.  

The closure is part of the $36.9 million project to replace the bridge over the CSX lines, and is necessary to allow crews to pour and set the new concrete bridge deck. During the overnight closure, motorists will be directed to the following detour routes: 

  • Northbound US 1: Take westbound I-195 to northbound I-95; go past I-695 to the ramp to southbound Caton Avenue; continue to Caton Avenue and turn right onto US 1 Alt. (Washington Boulevard).  
  • Southbound US 1: Turn right onto Selma Avenue; continue left onto Francis Avenue; then turn right onto Selford Road. Continue to South Rolling Road; turn right on to the ramp to I-195 East (Metropolitan Boulevard); take eastbound I-195; go past I-95 and continue to the ramp to US 1 (Washington Boulevard).
  • Clarke Boulevard to US 1 Alt.: Take Clarke Boulevard onto Selford Road; turn right onto Francis Avenue; take the Francis Avenue Bridge over Amtrak/MARC rail lines to Ridge Avenue; continue on Ridge Avenue to US 1. 
  • ​US 1 (Southwestern Boulevard) to Clarke Boulevard: From US 1 turn onto Tom Day Boulevard; turn left onto Carville Avenue; turn right onto Francis Avenue; turn left onto Selford Avenue and proceed to Clarke Boulevard.

In case of inclement weather, the bridge closure and detours will take place on the next possible Sunday night. 

NOTE: The intersection of the south end of Clarke Boulevard at US 1 will remain closed 24/7 until early 2023 for reconstruction of the intersection as part of the bridge replacement project. 

Once the concrete deck is poured and set, there will be temporary single-lane closures on US 1 in the vicinity of the bridge, when necessary, weekdays between 9 a.m. and 3 p.m. The bridge will remain open to traffic during temporary lane closures, with flagging to control two-way traffic.  

The overall bridge replacement project is expected to be complete by summer 2023. MDOT SHA contractor Lane Construction, of Glen Burnie, is performing the work.
