A blasting schedule for rocky sections of Highway 41 north of Road 208, where passing lanes are being constructed in both directions, was updated Thursday afternoon.
Project manager Anand Kapoor said the contractor, Teichert Construction of Sacramento, plans to start blasting next week, beginning April 28, from 9 a.m. to 2 p.m. during weekdays.
The work is expected to last for three weeks, which Kapoor said was “significantly less than previously estimated.” Delays are expected up to a maximum of 30 minutes, he said.
Rocky Cut, where a rockslide closed Highway 41 in January, is outside the project area and will not be included, though Caltrans officials said it is continually monitored.
The blasting adds to one-lane traffic controls that began earlier this month from 9 p.m. to 6 a.m. as crews work on the lanes. Those controls begin about 0.3 miles north of Road 208 next to the 22 Mile House and run the 1.7-mile-length of the project.
Kapoor said additional nighttime construction for drainage systems, roadway excavation, and an embankment are expected to take place on Sunday, Monday, and Tuesday, from 9 p.m. to 6 a.m. as well.
A detour is available for those who wish to avoid any delays. Northbound Highway 41 drivers can take a right turn onto Highway 145 and follow it along Road 211 until a left turn onto Road 200, which leads to Highway 41. Southbound drivers can follow the same route with a left turn onto Road 200, a right turn onto Road 211, and following it as it changes into Highway 145 back to Highway 41.
Teichert Construction’s $8.7 million bid was selected for the project over three competitors in July. The total project costs are $9.7 million. Work was set to begin in February, but the presence of threatened California Tiger Salamanders delayed construction.
