Marquette Lake Bridge at Fort Indiantown Gap
Little Buffalo Creek Bridge, Perry County
Our 2023 bridge project on Little Buffalo Road, Perry County was nominated for the Linda Atkinson Golden Hammer Award at PennDOT’s District 8 Winter School.
We performed a rehabilitation of an existing single-span steel bridge with prestressed concrete spread box beams along with abutment repairs, minor approach construction, traffic signing and paint.
Our unique feature of the design was the 3/4 inch recessed panel detail that was depicted for the bridge parapets. This made the bridge superstructure stand out compared to normal bridge parapet wall construction and enhanced the visual appeal..
