Jeffrey Road/Walnut Avenue Intersection Improvement

Jeffrey Road/Walnut Avenue Intersection Improvement

The City of Irvine proposes to improve the Jeffrey Road/Walnut Avenue intersection with the addition of a shared through/right-turn lane, and a second left-turn lane on Walnut Avenue in the eastbound direction. The widening improvements have been designed to accommodate an increase in traffic volumes for left-turn, through, and right-turn movement. The proposed land configuration includes two left-turn lanes, one through lane, a shared through/right-turn lane and a right-turn lane with widths of 10 feet (ft.), 10 ft., 11 ft., 11 ft., and 14 ft. respectively. These improvements would require Walnut Avenue to be widened 8 ft. to the south, with a final roadway width of 86 ft. Widening Walnut Avenue would also necessitate 8 ft. of additional right-of-way to be acquired to the south, resulting in a final right-of-way width of 106 ft. Located within the acquired right-of-way will be a Class III Sidewalk Bikeway. The limits of the widening on Walnut Avenue will span from its intersection with Jeffrey Road to approximately 185 ft. west of Wisteria Lane. The proposed project would require an approximately 3,750-square-foot permanent right-of-way acquisition. During construction grading, an additional 3,300-square-foot temporary easement will be required to allow for access and staging by the construction contractor.
