PROJECT OVERVIEW

The Caltrans District 11 State Route 78 (SR-78) Pavement Preservation project aims to extend the service life of the Asphalt Concrete pavement on SR-78 near Julian, CA. The project extents are from Postmile (PM) 37.2 to 60.0, from Hatfield Creek Bridge to 0.2 miles west of Wynola Road. The project also includes drainage system restoration, mobility, complete streets, and safety performance objectives.

PROJECT FEATURES

This project focuses on rehabilitating SR-78 by repaving sections with a durable asphalt mix. This rehabilitation work includes grinding the existing pavement and applying a new layer to improve the road's condition. For enhanced safety, the project will install rumble strips along the centerline and shoulders, designed to alert drivers and promote safe travel.

This project will also perform drainage improvements along SR-78 by replacing systems or lining existing systems. Throughout the historic downtown Julian, the project will upgrade Curb Ramps and install crosswalks.
