LEHIGH TWP., Pa. -

PennDOT is preparing to start a months-long project in Northampton County.

Crews spent the day Thursday putting up detour signs around the Walnut Drive bridge over Indian Creek in Lehigh Township.

The stone bridge has been deemed structurally deficient, so it will knocked down and replaced with a concrete arch bridge.

Drivers can expect detours in the area during construction, which is expected to wrap up next November.
