Updated 3:48 p.m., May 13, 2013: Caltrans updated press releases states that this project will cost $41 million.

Roadwork has already begun or is set to resume this summer on the West Shore on Highway 89 between Tahoma and Tahoe City, part of a $34 million project to help protect lake water quality by rehabilitating drainage and treatment systems, installing runoff collection and treatment, and adding curbs and gutters.

Caltrans’ work this year involves installing nine sand vaults between the Placer County line and Madden Creek. In conjunction with Caltrans’ improvement project, Southwest Gas and its contractors will be relocating and replacing natural gas lines from Pine Street in Tahoma up to Timberland Lane.

Motorists can expect one-way traffic controls at various locations on Highway 89 day and night through the construction areas, with up to 20-minute delays. There will be no lane closures on weekends and holidays.

Beginning in spring 2014, work will begin to realign the road, widen shoulders to allow for bicycles and places for vehicles to pull out of traffic, move the existing bike trail, lengthen existing left turn pockets and continuous left turn lanes, and construct new left turn lanes at Gray Avenue, Moana Circle, McKinney Rubicon Springs Road, Ward Avenue, Sunnyside Lane, Olympic Drive (north), Granlibakken Road, and the proposed entrance to Tahoe City Transit Center. The highway will also be completely resurfaced.

Construction is funded by federal storm water improvement money, and will last through five construction seasons until October 2016.

U.S. highway 50 in south Shore has four roadwork projects to continue through out the season.

Motorists are advised to allow for extra travel time. Work will not be performed on major holidays.
