I-81 Widening MM 317 to MM 319

This opportunity is a Design‑Build contract to widen a two‑lane segment of I‑81 in Frederick County, Virginia, from Mile Marker 317 to 319, and to upgrade the associated interchange and ramp. The work includes roadway expansion, bridge replacement, rail and utility coordination, flood‑plain culvert installation, and traffic‑control improvements. The contractor must submit a Statement of Qualifications covering a broad set of engineering and construction disciplines. • Expand I‑81 to three lanes each way between MM 317‑319, including three bridge replacements and two large box culverts. • Convert the existing I‑81/US 11 diamond interchange to a diverging‑diamond interchange with added park‑and‑ride and street‑carriage modifications. • Realign the northbound off‑ramp to eliminate a signalized intersection and consolidate traffic control. • Provide comprehensive engineering services (roadway, bridge, geotechnical, hydraulic, environmental, ITS, utility coordination, and right‑of‑way) and construction inspection/quality‑control. • Submit qualifications via Bid Express; a virtual project information meeting is scheduled for July 15, 2026.
