Interstate 5 Improvement Project from Interstate 405 to State Route 55

Interstate 5 Improvement Project from Interstate 405 to State Route 55

The project limits on I-5 extend from approx 0.4 mi north of the I-5/I-405 interchange (PM 21.3) to 0.2 mi south of SR 55 in the cities of Irvine and Tustin. The project proposes to remove the existing paved outside shoulders of the I-5 freeway and construct new traveled way and new shoulder pavement to the outside of the northbound and southbound lanes to accommodate one additional general-purpose lane in each direction from just north of I-405 to just south of SR 55. The existing buffer-separated HOV lane would be converted to a continuous access HOV lane, with continuous entry/exit opportunity for motorists, throughout the project limits.
