Caltrans is preparing to begin a maintenance project that will improve the roadway surface of Interstate 5 between Louise Avenue in Lathrop and Downing Avenue near the city of Stockton. 

 Work will include the repair of failed roadway surface locations using hot-mix asphalt, install new shoulder backing and new asphalt concrete dikes.

 Overnight, alternating lane closures on northbound and southbound I-5, as well as on and off-ramp closures at Louise Avenue, Lathrop Road, Roth Road and Downing Avenue, will be required for the safety of motorists, roadway workers and equipment. 

 Beginning July 10, crews will work mostly night shifts, with some daytime work, for approximately 45 days — Sundays through Fridays — with completion expected in October.  Overhead and roadside message signs will be placed on I-5 to alert motorists of scheduled highway and ramp closures.

 This $2.89 million project was awarded to O.C. Jones & Sons Inc. of Berkeley.

This project will benefit commuters traveling to and from the cities of Stockton, Lathrop and Tracy, as well as motorists, and truckers hauling commercial and agricultural goods throughout San Joaquin County and beyond.

 By improving the roadway surface, this project will also improve mobility and greatly reduce current and future maintenance repair costs for this highly traveled corridor. 

 For more information and updates on additional projects, please consider following our social media accounts on Twitter via @CaltransDist10 or Facebook at Caltrans, District 10 or visit www.dot.ca.gov/d10/projects.

 The work schedule is subject to change due to traffic incidents, weather, availability of equipment and/or materials, and/or construction-related issues.
