The need for this project stemmed from the existing condition in the westbound direction of S.R. 0063 in which only one through lane carried traffic across the existing culvert. Two westbound through lanes existed at the intersection of S.R. 0063 and S.R. 0113 but these quickly merged together into one lane at the culvert. Consequently, through traffic seldom used the second through lane and queue lengths in this direction increased significantly. The addition of a second westbound through lane has helped to improve the capacity through the S.R. 0063/S.R. 0113 intersection while also improving the use of the through lane as it ties into the right turn lane for the shopping center.
A critical component that needed to be addressed as part of this project was the existing culvert. This culvert required widening on the northern (upstream) side in order to accommodate the second through lane and maintain the existing roadway alignment of S.R. 0063 in this area. The existing culvert was a concrete arch culvert in good condition.
SCOPE OF IMPROVEMENTS
The S.R. 0063 Roadway and Structure Improvement project is located in Lower Salford Township, Montgomery County, PA. The proposed improvements along S.R. 0063 (Sumneytown Pike/Main St) for this project are located between the intersection of S.R. 0063 & S.R. 0113 and S.R. 0063 & The Shops at Harleysville. The improvements are approximately 800 LF in total length and will include the following:
• Widening westbound S.R. 0063 (variable width from 2’ to 17’) to accommodate additional westbound through travel lane.
• Culvert Extension on S.R. 0063 to accommodate additional westbound through travel lane.
• Geosynthetic Reinforced System
• Sidewalk installation between the S.R. 0063/S.R. 0113 intersection and the S.R. 0063/Shops at Harleysville intersection.
• Traffic Signal Permit Plan modification for the existing signal at the S.R. 0063/Wal-Mart Shopping Center access.
The project was identified by Lower Salford Township and McMahon Associates, Inc. The commitment by the Township was to advance the engineering phase through the PennDOT Highway Occupancy Permit process so that once construction funding became available, they would be able to act swiftly in advertising and letting the project for construction. The project was designed and permitted through PennDOT. At the time the Department of Community and Economic Development and Commonwealth Financing Authority announced their initial Multimodal Transportation Fund Program in 2015, Lower Salford Township prepared their application with a shovel ready project and approved construction plans. Lower Salford was awarded $787,810 for the construction of the project. The project was prepared for advertisement and letting in the Fall of 2016 following the grant award announcement in July 2016. Construction began in the Spring of 2017 and was complete in June 2018. The designer was McMahon Associates, Inc. and the prime contractor was Flyway Excavating, Inc. The overall project construction cost was approximately $881,100. Local Township funds from the Act 209 program were used for the required 30% match.
