County:Washington Project Number:WA344_52
IS 0081 MARYLAND VETERANS MEMORIAL HIGHWAY IHB - SOUTH OF US 11 IN WEST VIRGINIA TO NORTH OF MD 63/68
Project Name:
I-81, Maryland Veterans Memorial Highway

Location of Project:
IHB - SOUTH OF US 11 IN WEST VIRGINIA TO NORTH OF MD 63/68

Description:
Upgrade and widen I-81 from US 11 in West Virginia to north of MD 63/MD 68 (3.6 miles). West Virginia is funding improvements in West Virginia and Maryland is administering this bi-state project. This is Phase 1 of a four-phase project.
 
Scope:
This project involves the widening and rehabilitation of the existing dual bridges on I-81 over the Potomac River at the Maryland/West Virginia state line. The dual structures carry a current average daily traffic volume of 61,300 with a projected average daily traffic volume of 84,375 in 20 years. The structures are 1136+’ long and provide clear roadway widths between barriers of 30 feet. The bridges cross the C&O Canal National Historic Park, the Potomac River and extend into West Virginia. This project is being coordinated with the National Park Service and West Virginia.

While the bridges are not currently structurally deficient, the roadway surface for each bridge is 47 years old, they carry heavy truck traffic, and are beginning to show signs of advancing deterioration with the need for patching.

Considering the narrow width of the existing bridges we studied how the bridge improvement operations could best be completed with minimal disruption to traffic. After widening each bridge into the median to carry the current two lanes of traffic we are able to complete the replacement of the existing bridge surface in a single phase. The end result will be bridges capable of carrying a future third lane widening with full width shoulders along I-81 for both directions through Maryland into West Virginia.

These bridges are Maryland’s responsibility for management and maintenance. West Virginia previously completed the widening of I-81 to three lanes in each direction, from Martinsburg to just north of the US 11 interchange in West Virginia. In order to provide the third lane widening into Maryland, West Virginia requested Maryland to include continuous widening of I-81 into project from the current point north of their US 11 Interchange to the Maryland State line. This additional widening will be included in the project with West Virginia reimbursing Maryland for the additional costs. The resulting project will provide for a third lane in each direction from north of the MD 63/68 interchange, southward to Martinsburg, West Virginia.
