State Route 138 Widening Project from Avenue T to State Route 18 Through Palmdale, Littlerock, Pearblossom and Llano

The project involves widening State Route 138 from post mile 66.0 to 68.5 in Los Angeles County, California, from two lanes to four lanes, with each direction featuring two 12-foot travel lanes and an 8-foot shoulder separated by a 16-foot two-way left-turn median to increase capacity. Additional traffic striping improvements without adding new lanes are required on SR 138 from post mile 68.5 to 70.1 and on SR 18 from post mile 3.4 to 4.5.
