Central Avenue Safety Project

centralavenue.png

The Central Avenue project is expected to improve safety for all street users and to reduce vehicle delays.  The project includes a road diet with two motor vehicle travel lanes, a two-way left-turn lane as a center lane, bikeways, three funded roundabouts at 1) Main/Pacific/Central; 2) Third/Taylor/Central; 3) Fourth/Ballena/Central, resurfacing, improved bus stops, enhanced pedestrian crossings and street trees/raingardens.  

Status: City Council approved the concept in 2021 with four roundabouts, and approved additional funding for three of the roundabouts in spring 2023.  As of June 7, 2024, Caltrans authorized the City to start the construction phase with three funded roundabouts. The roundabout at Sherman/Encinal/Central is unfunded.  Construction is expected in late-2024.

The project area is along Central Avenue between Pacific Avenue/Main Street and Sherman Street/Encinal Avenue.  Central Avenue is in school and recreation zones, an island arterial and a truck and transit route.  Central Avenue is designated as Caltrans State Highway 61 between Webster Street and Sherman Street.  Sidewalks and on-street parking exist on both sides of the street.  No bikeways exist except for a path between Pacific Avenue and Lincoln Avenue.  AC Transit Lines 20, W, 631 and 661 run along Central Avenue mainly between Webster Street and Eighth Street.  

Why this project?

The Central Avenue study area has a disproportionate number of injuries from collisions compared to other streets in the city.

Road Diet Concept
The reduction of motor vehicle travel lane(s) is recommended in that it provides an opportunity to reallocate space for other uses such as bike lanes and a center two-way left-turn lane.  According to the Federal Highway Administration's informational guide(PDF, 2MB) , streets with travel lane reductions have multiple benefits for people driving, walking and bicycling, such as:
  • Decreases vehicle travel lanes for pedestrians to cross;
  • Allows for better visibility of pedestrians waiting or attempting to cross the street;
  • Improves circulation for bicyclists when a bikeway is added;
  • Reduces rear-end, sideswipe and left-turn collisions by at least 19 percent and up to 47 percent through the use of a center two-way left-turn lane;
  • Improves speed limit compliance by three to five miles per hour, which reduces the severity of collisions; and
  • Improves travel flow since through vehicles are separated from left turning vehicles.

The Federal Highway Administration (FHWA) also has issued a case studies document as well as additional resources.  FHWA Video and Fact Sheets are as follows:

Roundabouts Concept

Roundabouts reduce the types of crashes where people are seriously hurt or killed by 78-82 percent when compared to conventional stop-controlled and signalized intersections, per the AASHTO Highway Safety Manual.  Roundabouts result in lower vehicle speeds, generally 15-25 miles per hour, around the roundabout.  Crashes that occur will be less severe because of this reduced speed and the more “sideswipe” nature of crashes.  Pedestrians are generally safer at roundabouts, and are faced with simpler decisions at a time. Videos and presentations on roundabouts are as follows:

- Why: City staff/consultant team recommended approval of the final concept including the Webster Street area and roundabouts.  The City Council approved the final concept including the four roundabouts with the Sherman Street/Encinal Avenue roundabout as a slip lane and not a cul-de-sac. The City staff/consultant team are working to complete the environmental clearance this year and the design next year with construction expected to begin in late 2022. Please note that only two of the four roundabouts are funded, and City staff is seeking more monies for the Fourth Street/Ballena Blvd./Central Avenue and Sherman Street/Encinal Avenue/Central Avenue roundabouts.
