Airport Access Road

PennDOT District 3-0 | Lycoming County, PA

This work consists of providing engineering services and environmental studies services for a roadway project, S.R. 0180, Section 048, connecting the Williamsport Regional Airport with the Warrensville Interchange of I-180 in Loyalsock Township and Montoursville Borough, Lycoming County, Pennsylvania. The project consists of constructing approximately one mile of roadway with two structures on a new alignment and includes some railroad relocation and coordination. The first structure is a bridge over the railroad, and the second will carry the new roadway and the relocated railroad over Loyalsock Creek. S.R 2088, also known as Airport Access Road, is proposed as “a new two-lane roadway to provide improved access to and from the Williamsport Regional Airport and Interstate 180.” The proposed project will increase safety by providing a direct connection to Interstate 180, eliminating the need for airport traffic to use local streets.

AEG also conducted a hydrologic and hydraulic study that was undertaken to analyze the hydraulic impacts of the proposed construction of the S.R. 2088 (Airport Access Road) bridge over Loyalsock Creek. The project area is located within a Federal Emergency Management Agency (FEMA) regulated 100-year floodplain and floodway boundary. A regulatory 100-year floodplain and floodway are established for the Loyalsock Creek at the project site. The floodway at the proposed project site is approximately 1,800 feet wide and is contained within the existing bridge abutments and within the levee flood control project.

This Hydrologic and Hydraulic Report will address the hydraulic impacts and floodplain effects of the proposed bridges over Loyalsock Creek. Impacts will be reported and analyzed for proposed conditions both with and without the proposed United States Army Corps of Engineers (USACE) levee.

AEG also prepared a Reconnaissance Soils and Geological Engineering Report that obtained all pertinent information to the site and its history, reduced the scope and cost of a drilling and sampling program by using existing information, and predicted geologic hazards.
