Priority II Projects: Secondary improvements that were determined as part of the future conditions analysis, and offer support to Priority 1 projects. These projects are more targeted and may eventually be considered for regional and local transportation plans.

Location

Creekside Drive Issues Project Description Operations Sketch Concept

▪ Under future conditions, northbound right operates at LOS E (LOS F for shared thru/left movement) ▪ Under future conditions, queuing for the northbound right exceed 600’.

Creekside

▪ Widen the connector at Creekside

Drive to accommodate dual northbound right turn lanes. ▪ Install pedestrian crossings and countdowns.

▪ Under future conditions, extensive queuing occurs, primarily with movements associated with

Nationwide Drive. ▪ Under future conditions, several movements will operate at LOS F, including the overall intersection during the PM peak.

Millrace Drive

▪ Under future conditions, the eastbound right meets turn lane warrants, per VDOT standards. ▪ Install a full size roundabout with a raised island. ▪ Maintain the eastbound right slip lane.

▪ Provide an eastbound right turn lane. ▪ Maintain existing access, but consider bringing north side driveway into signalization.

Priority II Projects: Secondary improvements that were determined as part of the future conditions analysis, and offer support to Priority 1 projects. These projects are more targeted and may eventually be considered for regional and local transportation plans.

Location Issues

Millrace Drive to Millside Drive

▪ Numerous accidents clustered near the Lillian Lane intersection. ▪ Difficulty making an eastbound left and southbound left. ▪ High speeds and steeper grade along this portion of Graves Mill

Road. ▪ Under future conditions, the eastbound and westbound left movements at Millside Drive meet turn lane warrants, per VDOT standards.

Project Description Operations

▪ Provide a landscaped median with left turn lanes between Millrace Drive and

Millside Drive. ▪ The landscaped median would connect with the westbound left at Millrace Drive and support the potential Millside Drive improvements as dedicated left turn lanes. ▪ The improvement would require widening Graves Mill Road to accommodate the additional lane. ▪ The project would be enhanced by a multiuse path or sidewalk along the south side of Graves Mill Road (previous multimodal recommendation). ▪ The landscaped median should help to reduce the occurrence of rear-end crashes associated with eastbound and westbound lefts. ▪ if full access opening is not considered for the landscaped median, northbound and southbound lefts could make u-turns at the nearest signalized intersection.

Priority III Projects: Building on Priority II Projects, these recommended improvements will be needed if a maximum buildout and growth scenario occurs along the corridor. Priority III projects should be monitored over time as conditions dictate.

Location

Old Graves Mill Road and Creekside Drive Issues

▪ Under future conditions, heavy eastbound movement results in long delays, particularly for westbound left movements (priority given to Graves Mill Road). ▪ Lane bias may remain an issue with only two lanes. ▪ Eastbound queuing over 1,000’ at Old Graves Mill Road. ▪ Queues extends beyond available storage for several left turn lanes.

Sketch Concept

Priority I

Old Graves Mill Road Priority II project included as part of complete concept design.

Note: Future study needed to identify appropriate intersection for Old Graves Mill Road and Connector Road.

Project Description

▪ Provide an additional eastbound through lane, beginning west of Old

Graves Mill Road and connecting with the Priority I lane addition at

Creekside Drive. ▪ Provide dual westbound left turn lanes at Old Graves Mill Road. This will require two receiving lanes on Old Graves Mill Road. ▪ The additional northbound right at Creekside Drive included as part of complete concept.
