College Avenue in Elizabethtown Borough was in need of more efficient transportation infrastructure to decrease traffic congestion and hazards as well as improve traffic flow.
To accomplish this goal, RETTEW split the project into two phases. The first phase relocated an existing borough street to avoid placing heavy traffic in local neighborhoods with small intersections, infringing on vehicle turning.

The second phase of the project involved improved access to one of the Borough’s largest employers, M&M Mars Company. This phase involved demolishing an existing car repair facility with known leaking underground storage tanks and hazardous materials. RETTEW also improved a stream flowing through the project site, which included rehabilitating a historic millrace, widening and constructing a new road, building a new bridge, installing two traffic signals, and incorporating a new entrance to Elizabethtown. The project received federal, state, and local funds and transformed the gateway to the Elizabethtown area.
