The City Council on Tuesday approved a plan to narrow Alamitos Avenue to one lane in each direction and install parking-protected bike lanes in the latest of several projects designed to make roadways safer for pedestrians and cyclists.

The “road diet” would cover about a half-mile stretch of Alamitos Avenue, from Ocean Boulevard to Seventh Street. It would also create a two-way left turn lane in the middle of the roadway, similar to a reconfiguration done last year on Alamitos Avenue, from the north side of Seventh Street to Pacific Coast Highway.

A timeline for the project has not been created yet, according to city traffic engineer Eric Widstrand, who said workers may try to schedule it at the same time as other road improvements underway in the area, including the East Broadway “road diet,” which will narrow a 1.5-mile stretch of the roadway from four to two lanes between Temple and Alamitos avenues.

The project cost has also not been determined yet because it has not been put out to bid, however, he said it could cost approximately the $500,000.
