STARS Project Development Cycle
SIX-YEAR IMPROVEMENT PROGRAM
Study/Project Development Cycle
Advancement of STARS projects is tracked as a measure of performance in the VDOT Business Plan.
DID YOU KNOW? 73% of STARS studies have resulted in projects being funded in SYIP.
2007 to Today – 283 Studies
Project Summary SheetsSTARS one-page project summary sheets have proven to be an effective tool for summarizing several important project features, especially those factors that are required in many of the potential funding applications.
PROJECT DESCRIPTION The proposed improvement includes constructing a 600-foot northbound
Lynchburg Expressway auxiliary lane between the entrance ramp from eastbound Candlers Mountain Road and the exit ramp to westbound CandlersMountain Road, constructing a 700-foot southbound Lynchburg Expressway auxiliary lane between the entrance ramp from westbound CandlersMountain Road and the exit ramp to eastbound Candlers Mountain Road, and realigning the northbound Lynchburg Expressway entrance ramp from westbound Candlers Mountain Road to increase the curve radius and meet the minimum AASHTO recommended design length.
The improvement includes replacing the Candlers Mountain Road bridge.

Constructing the northbound and southbound Lynchburg Expressway auxiliary lanes at the Candlers Mountain Road interchange will improve safety by providing longer acceleration and deceleration distances for vehicles merging onto and off of the Lynchburg Expressway. In addition, realigning the northbound Lynchburg Expressway entrance ramp from westbound CandlersMountain Road will allow vehicles to reach a higher speed before merging onto the Lynchburg Expressway.
