 Highway 46 Corridor Improvement Project


The widening of Highway 46 East from one lane in each direction to two lanes in each direction began in 2008 with a $35 million project from Airport Road to Geneseo Road.  This project was completed was completed in 2011.

The second phase of widening Hwy. 46 East from Geneseo Road to east of Almond Drive is now under construction.  This $47 million project is expected to be completed in late 2014/early 2015.  A milestone event was held in May 2014 to celebrate the opening of the Estrella River Bridges, a major component of this project.   

Hwy. 46 East is also currently being widened from east of Almond Drive to McMillan Canyon Road near Shandon.  This $38 million project began in 2013 and is expected to be complete in 2015.

Caltrans is in the design stage to widen Hwy. 46 East from McMillan Canyon Road to the Shandon Roadside Rest Area. Construction on this $88 million widening of Hwy. 46 East could begin on 2016.

These widening projects are expected to decrease the number of multi-vehicle accidents that have occurred for several years within this corridor and will improve safety for the thousands of commuters and visitors from the central valley who frequent the central coast.  The agricultural and trucking industries will also benefit from a safer highway as they transport goods in and out of San Luis Obispo County.  Caltrans District 6 in the San Joaquin Valley has already completed widening much of Hwy. 46 East in Kern County.
