In March 2019, the CTC approved for future consideration of funding a
project is located on various locations along Route 299 and Route 139 in
Lassen and Modoc Counties (02-Las-299, PM 18.5/25.6, 02-Mod-299, PM
0.5/0.5, 1.1/1.8, 02-Mod-139, PM 0.1). This project proposes to reduce the
amount of distressed lane miles by restoring the roadway to a condition of
minimal maintenance for a 20-year design life. This proposed project
addresses the existing poor pavement condition, late stages of
deterioration, and the roadway’s substandard lighting. The project
also proposes widening shoulders, reconstruct driveway approaches, and
updating the Intelligent Transportation System (ITS) elements. This
project is fully funded and programmed in the 2018 SHOPP for approximately
$25.2 million, construction is estimated to begin in 2020. The scope, as
described for the preferred alternative, is consistent with the project
scope programmed by the Commission in the 2018 SHOPP.
