Document Description
The proposed project improvements include the following: 1) on northbound Harvard Avenue – re-stripe to lengthen left-turn lane, maintain two through lanes, and restripe to provide a de facto right turn lane; 2) on southbound Harvard Avenue - add one left turn lane for a total of two left-turn lanes, maintain two through lanes and one right turn lane, provide a Class II on-street bike lane towards intersection stop line, add 10-foot off-street shared use path for bikes and pedestrians; 3) On eastbound Michelson Drive – maintain two left-turn lanes, two through lanes and remove non-standard free right-turn lane and replace with designated right-turn lane, add a 10-foot off-street shared use path for bikes and pedestrians; narrow west end of existing median; 4) on westbound Michelson Drive - maintain one left-turn lane, two through lanes, restripe to provide a Class II on-street bike lane towards intersection stop line; 5) on the northwest corner - remove existing right-turn lane into Irvine Lanes driveway and provide a 7-foot striped on-street bike lane with 3-foot buffer; and 6) other supporting improvements with signage, traffic signals, streetlights, utility relocations, drainage and water quality improvements, retaining walls, landscape, and lighting. The proposed Project is one of the mitigations identified in both 2010 and 2015 Irvine Business Complex (IBC) Vision Plan Traffic Studies and would improve circulation in both the short- and long-term to the intersection by providing capacity enhancements and improve circulation.
