California State Route 149

State Route 149 (SR 149) is a short state highway that helps to connect Oroville and Chico through rural Butte County. Connecting State Route 70 at Wicks Corner with State Route 99 east of Durham, it forms part of the primary north–south highway through the eastern Sacramento Valley, a Focus Route of the Interregional Road System. SR 149 was formerly part of the Oroville-Chico Highway; the majority of the latter was merged into other routes. In the mid-1970s, the highway was reallocated onto a newer two-lane alignment. The route is also part of the California Freeway and Expressway System, and a project to widen the two-lane road to a four-lane expressway was completed in late 2008, removing the bottleneck from the Oroville-Chico highway.
