STAUNTON - The Virginia Department of Transportation will hold a public hearing concerning improvements to the Interstate 81, exit 310 interchange at Route 37 in Frederick County.  The meeting will take place on Thursday, May 24, 2012, from 4 p.m. to 7 p.m. at Robert E. Aylor Middle School, 901 Aylor Road, Stephens City, Va. 22655.

Citizens can come in during the meeting hours and discuss the project on a one-on-one basis with VDOT officials and designers. Written comments can be submitted at the meeting or within 10 days after the meeting date to Mr. Scott Alexander, Project Manager, Virginia Department of Transportation, 811 Commerce Road, Staunton, VA  24401-9029. Oral comments can be recorded at the meeting with the assistance of a court reporter.

This project will reconstruct the interchange ramps on Interstate 81, Exit 310, at Route 37 (south) in Frederick County.  The interchange configuration will feature a “spread diamond” interchange, which will widen and spread the ramps outward from their current intersections with Route 37.  This design provides additional turn storage and adds dual left- and right-turn movements to move traffic more efficiently.  

The interchange is being designed with future “scalability”, which can accommodate changes in traffic patterns and traffic volumes. The design can accommodate conversion of the interchange to a partial cloverleaf, a full cloverleaf with collector-distributor lanes, or a multi-level semi-directional interchange. As part of the design contract, the consultant will produce preliminary designs for the final interchange configuration, ensuring that the spread diamond design accommodates and facilitates future phases, as neighboring development and traffic patterns demand more of the interchange.

The final build-out of the interchange will be done in several future phases.

In association with the interchange improvements, the Crosspointe developer will continue the extension of Route 37 east of I-81 and build it as part of their construction site.

The Federal Highway Administration approved the Interchange Modification Request (IMR), on April 18, 2007. The IMR consists of a three-phase approach to improving the interchange.

Phase one includes the design for the spread diamond configuration, right of way acquisition, utility relocations and construction of the spread diamond interchange. The estimated cost is $48.0 million.

Phase two may include a partial cloverleaf loop and/or widening of the Route 37 bridge over I-81. All phase two work depends on future traffic demand and available transportation funding.

Phase three may be the completion of cloverleaf or flyover ramps. The cloverleaf option may also include collector distributor lanes. Collector distributor lanes run parallel to the interstate roadway, taking traffic of the mainline a mile to half mile prior to the interchange ramps. All phase three work depends on future traffic demand and available transportation funding.

The total estimated cost for this project is $48 million, including $4.6 million for preliminary engineering, $4.2 million for right of way and $39.2 million for construction.

On Interstate 81 in 2015 traffic counts for this location are projected to be 57,270 southbound, south of Route 37 and 51, 189 northbound, north of Route 37.  In 2035 traffic counts for this location are projected to be 85,100 southbound, south of Route 37 and 76,064 northbound, north of Route 37.
