Starting Aug. 12 for approximately two weeks, The Alameda from Hopkins Street to Solano Avenue will be put on a “road diet.” It will be restriped from four lanes to three, with outside lanes for traffic, a center lane for left-hand turns, and dedicated bike lanes for cyclists and right turns.

Once complete, The Alameda will have a cross section similar to Marin Avenue. The work extends from Solano to just south of Hopkins and involves grinding out existing lane markings, laying out the new marking locations on the asphalt (cat tracking), city approval of the layout, and installation of permanent thermoplastic markings.

The Alameda will remain open to traffic with localized lane closures and shifts as the work proceed, but parking along this stretch will be prohibited during construction. Officials say there may be traffic delays but no road closures.

The Alameda’s “road diet,” headed by the Office of Transportation and Councilman Laurie Capitelli, comes out of a three-year process that explored ways to make The Alameda safer for pedestrians and bicyclists with minimal impacts on auto traffic.

The project’s goals include improving pedestrian safety, improving the safety of left turns, improving safety for exiting parked cars, creating bike lanes, and reducing traffic speeds, along with the specific goals of providing room for The Alameda residents to back out of their driveways and getting rid of the southbound merge lane below Hopkins.

In 2005, Marin Avenue was put on a similar diet, in which a stretch of the road was downsized from four travel lanes to two, and a two-way turn lane and bicycle lanes were added to improve safety for motorists, bicyclists and pedestrians. However, injury accidents actually increased after the diet, according to one analysis, implying that this type of fix is not necessarily effective for every street.
