The City of Calabasas has rolled up its sleeves on a pair of street and sidewalk improvement projects that will help traffic flow and provide greater safety for pedestrians along a three-mile stretch at the city’s southern border. The combined jobs have been more than three years in the making.

The current Mulholland Highway Gap Closure Project includes bicycle and pedestrian improvements to more than 1,000 feet of roadway on both sides of the Mulholland Old Topanga intersection near Calabasas High School.

The $3.4-million project eliminates gaps within the bicycle and pedestrian network along Mulholland Highway and Old Topanga Canyon Road. It also widens sections of Mulholland Highway, installs new irrigation and landscaping, adds new retaining wall and reduces side slope. Access for bicycles was greatly improved.

An Edison power pole was also removed.

“Other utility work still needs to be done, guardrails will soon go up, and final paving will start soon,” Mayor Mary Sue Maurer said in a message to residents.

Completion date is midto late March. The city used various funding sources from state and county coffers to pay for the work.

A separate job known as the Mulholland Highway Improvements project is currently in the design phase.

The project is separated into three steps. The limits of Phase I are between the two intersections with Old Topanga Canyon Road with work that includes shoulder improvements, construction of retaining walls, roadway widening, extension of the eastbound left turn lane onto Old Topanga Canyon Road, installation of guardrails, a new sidewalk on the south side of Mulholland, Wild Walnut parking lot improvements, and a traffic signal installation at the intersection of Old Topanga Canyon.

Estimated construction cost of the first phase is $2.8 million with a total cost of the project coming in at around $12.6 million.

Phases II and III will include stabilization of erosion prone slopes, new passing lanes and improvements at the Viewpoint School frontage that include a right turn lane.

The construction start of Phase I is projected for June 2022 with a public workshop scheduled for next month.

The Mulholland Highway Improvements are funded by Los Angeles County Measure M transportation funds.
