This federally funded Capital Improvement Program (CIP) project is for improvements to Gas House Pike at Linganore Creek for the replacement of two existing structures, a larger multi-cell structure known as Gas House Pike Bridge (Structure No. F09-21) and a nearby smaller multi-cell pipe structure just west of Gas House Pike Bridge, which will become a new bridge (Structure No. F09-25). The proposed project work will include complete removal of both existing structures, installing a single 77' span prestressed girder bridge with concrete substructure and caisson foundation, installing a single 52' span prestressed girder bridge with concrete substructure and caisson foundation, installing new bridge railings, replacing portions of the existing traffic barriers, installing new traffic barriers and end treatments, installing pipe culverts and headwall, installing storm water management facilities, installing roadway drainage improvements, installing a 10" diameter sanitary sewer line with associated items, 12" diameter water line with associated items, regrading approaches, placing full depth pavement and tying grading into existing topography. The bridge structures and roadway approaches will have two 11-foot lanes with 5-foot shoulders to meet collector standards. The CIP project will provide needed safety improvements and reduce the frequency of flooding at this location.
Final Design for this project is nearly complete and advertisement is anticipated for late April/early May 2019. Once the project contract has been awarded, a Notice-to-Proceed (NTP) will be determined for the start of construction. Construction start is anticipated for late summer/early fall 2019. The project requires a full-time road closure for the duration of construction and completion of the project. Project duration is estimated to be 450 calendar days. After NTP has been given, advance notification of the bridge closure will be posted at the bridge site and sent via public notification.
