Project Location: Frederick County, VA
Project Description: The Virginia Department of Transportation in cooperation with Frederick County has conducted a study of alternative improvements to the proposed extension of VA Route 37 Bypass with proposed interchanges at Warrior Drive and US 522. The extension of VA Route 37 east of I-81 to US 522, and beyond, has been in the planning process for over 20 years. In recent years, the project has evolved to the Interchange Justification Report (IJR) stage by the prompting of a Tri-party agreement in 2012 between VDOT, Frederick County, and the Crosspoint developer Glaize Developments, Inc. Crosspoint encompasses nearly the entire length of the proposed VA Route 37 extension to US 522. The preferred alternative improvement selected by the study provides flexibility in order to serve an uncertain future based largely on future development.
T3D’s Role in Project: T3 is developing an Interchange Justification Report (IJR) for two proposed interchanges to be located on new alignment on the Route 37 Bypass south of Winchester, Virginia. The two proposed interchanges are to be located at Warrior Drive, which is to be extended on new alignment up to the proposed Route 37 alignment, and an additional interchange at Route 522 (Front Royal Pike). The detailed T3 work include the followings.
- Traffic volume projections, in coordination with MPO travel demand models and other studies done for the project and for adjacent private development.
- Preparation and calibration of CORSIM models for the weekday AM and PM peak travel hours.
- Complete a safety analysis based on AASHTO’s Highway Safety Manual methodologies.
- HCM and CORSIM analyses for Existing Conditions and design alternatives for build and no-build conditions for the opening year and the design year.
- Develop the operational analyses required to support the IMR and document final recommendations for changes to improve both operations and safety.
- Analysis of alternative travel modes for the area, including bus and train routes.
- Complete freeway, weave, and ramp junction analyses to identify and quantify potential upstream and downstream traffic impacts.
- Complete a conceptual signing plan for advance guide signs on the new bypass facility and proposed exits.
- A preliminary traffic control device plan for the preferred alternative that may include lighting and signals at the interchange ramps, and a construction cost estimate.
- Prepare materials and simulations for public involvement and attend stakeholder and citizen information meetings, as well as a design charrette.
- Coordinated improvements at the western end of this project at I-81 Interchange 310, where the proposed bypass will terminate at a separate interchange improvement project and the Crosspointe Development.
