Pennyfield Lock Road Bridge (M-0198B)

This project provides for the replacement of the existing Pennyfield Lock Road Bridge over a tributary to Muddy Branch. The existing bridge, built in 1930, is a single concrete slab structure. The existing clear roadway width is 14'-3" with one lane on the bridge carrying two-way traffic. The proposed replacement bridge includes a single span prestressed concrete beam structure carrying a 12'-0" traffic lane and two 2'-0" shoulders for a total width of 16'-0". This width will allow for the implementation of safe on road bicycling, in accordance with the Master Plan. The replacement bridge will be on a new alignment to the west of the structure. Park access is maintained while the existing bridge remains open during construction of the proposed bridge. Accelerated bridge construction techniques will be utilized to minimize the distruption to the travelling public and local community.

  • The design of the project is expected to finish in the Winter of 2014.
  • The construction is scheduled to start in Summer 2016 and be completed in Fall of 2016.
