Also this week, a few rural roads get long needed rehabs, and Porter Creek Road closes Wednesday night while bridge girders are delivered.

Porter Creek Road will be closed from 7 p.m. Wednesday through 7 a.m. Thursday while contractors deliver pre-cast girders to the project. There will be a moving road closure on Mark West Springs Road beginning around 7 p.m. for the four girders to be moved up the road from Hwy 101. Porter Creek Road will be closed at Franz Valley Road through the night while the girders are being set.

City crews continue work at the intersection of Mendocino Avenue and Bicentennial Way, with lane closures snarling traffic between 8:30 a.m. and 4:30 p.m. weekdays. The project will add new right turn lanes but involves excavating for an underground traffic signal and street light conduit. That work is complicated by its close proximity to existing gas, electric, water and communication facilities, city traffic engineer Steve Dittmer said. After that work is done, the new turn lanes will be excavated and paved, with the final paving done at night. Expect it to be done in September.
