Work began April 9 on a project to replace the structurally deficient PA 100 Bridge (locally known as the Passmore Bridge) over the West Branch of Perkiomen Creek in Washington Township, Berks County.

During the first phase of construction, the contractor is building a temporary roadway and two-lane bridge to carry traffic over the West Branch of Perkiomen Creek. The temporary bridge is scheduled to be complete by August.

Once the temporary bridge is complete, the second phase of construction will begin and entails closing the 74-year old PA 100 Bridge with traffic being shifted onto the temporary bridge.

Then, during the third and final phase of construction, traffic will be shifted to the new bridge with the temporary bridge being removed.

During all phases of construction traffic on PA 100 may experience sporadic, short-term lane restrictions between Gehringer and Niantic roads. Updates will be provided when available.

The project also includes construction of new bridge roadway approaches, guiderail, drainage improvements and other miscellaneous construction.

Work is scheduled to be complete in August 2014.

Mumford & Miller Concrete, Inc. of Middletown, Del. is the general contractor on the $1,953,476 project.

The Passmore Bridge is a steel I-beam bridge originally constructed in 1939. It is 95 feet long and 40 feet wide. The new bridge will be a 116 feet long, 41 feet wide two-span concrete box beam bridge. This section of PA 100 has an average daily traffic volume of 17,131 vehicles.
