This project includes widening MD 185 and Jones Bridge Road in three (3) phases to improve the capacity of the intersection. The project involves the design of the following: 1) widening southbound MD 185 to the outside to add an exclusive right-turn lane from the I-495 (Capital Beltway) off ramp to the subject intersection; 2) widening northbound MD 185 to the median to add a fourth through lane as an exclusive right-turn lane to the I-495 on ramp; 3) widening west leg of Jones Bridge Road to add an additional left-turn lane and provide longer storage lanes for the existing left turn lanes; 4) widening east leg of Jones Bridge Road to provide two through lanes and two right-turn lanes; 5) other improvements include sidewalk improvements, replacing existing curb and gutter, reconstruction of traffic signals, landscaping, bus stop and transit improvements, right of way coordination and acquisition, and storm drainage improvements, and Storm Water Management (SWM) improvements, which includes installation of two micro-bio retention facilities, underground storage facilities and porous sidewalks to remediate environmental impacts.
