Recommended Solutions • Short Term – Alternative 2 – Install traffic signal at Jones Bridge Road and Spring Valley Road » Impact of queuing along Jones Bridge Road » Complete in advance of BRAC action; funding exists » Exclusively within County DOT’s jurisdiction
Recommended Solutions • Long Term – Alternative 3 – Extend Platt Ridge Dr. to Montrose Driveway and modify existing traffic signal. • Access is least affected by queues along MD 185 and along Jones Bridge • Time to plan, design, construct; compete for funding • Requires involvement/cooperation of MNCPPC • Can not be implemented prior to BRAC action
