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.

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.
