Little Cedar Creek Pedestrian Bridge

Trexler Memorial Park, City of Allentown, Lehigh County, PA

The Little Cedar Creek is a Class “A” Wild Trout Stream in Trexler Memorial Park that is prone to flooding and bank erosion because of extensive residential and commercial development in the upstream watershed. MKA completed preliminary and final design, performed environmental studies, obtained all regulatory permits and approvals, and performed construction inspection for replacement of an existing undersized box-culvert that carries the bicycle and pedestrian pathway in Trexler Memorial Park across the Little Cedar Creek. The incorporation of spread footers into the substructure design allowed for re-establishment of a natural stream bottom under the new structure. In addition to protecting the historic Trexler Cabin site from flooding, this project also expanded the floodway upstream and on the side of the stream opposite the cabin.

Attributes
  • The new stream crossing is a pre-cast concrete arch bridge featuring parapets and wingwalls aesthetically faced with random ashlar stone.
  • Fish habitat enhancement structures designed to be consistent with the principles of fluvial geomorphic design were installed, and the streambanks along 1,250 linear feet of stream corridor were stabilized using biodegradable geo-textiles and ecologically appropriate native vegetation.
