Central Avenue Safety Project

Status: (Updated 10/27) Stage 2 ends today, Monday, 10/27. Stage 3 begins Wednesday, 10/29. Continue reading for details. As we approach the completion of the first two roundabouts, learn how to navigate them HERE.

Stage 2 was completed Monday, 10/27

With construction work mostly complete along Central Ave between Lincoln Ave and Fifth St (in front of Encinal School and Paden Elementary), two-way traffic along this stretch has resumed. One-way, northbound-only traffic is still in effect along Central Ave between Lincoln Ave and Pacific Ave/Main St. With the most substantial construction now complete between Lincoln Ave and Fifth St, two-way traffic along this stretch resumes Monday, 10/27. 

 Stage 3 begins Wednesday, 10/29

Stage 3 Construction involves temporarily closing the intersection of Central Ave/Pacific Ave/Main St while the roundabout is built. The Main Street Soccer Field and the businesses at 1930 Main St remain open during construction. Local traffic to these locations will be allowed to travel south from W. Atlantic Ave or Ralph Appezzato. See the Detour Map below. This final stage of construction is expected to end in Spring 2026, subject to delays due to weather and other unforeseen circumstances.

Slurry Seal begins Monday, 11/3

Slurry seal between Webster St and Sherman St is scheduled to take place the first week of November. Residents and businesses directly impacted by slurry seal will be contacted directly with more information.

Parking conditions along four key sections of Central Ave (updated 10/28):

Lincoln Ave to 5th St:

  • Street parking is not permitted
  • Two-way traffic has resumed

5th St to Page St:

  • Parking is permitted on the north side of the street up to midway between Webster St and Page St
  • Some temporary parking during construction is permitted on the outermost lane on the south side of the street, just west of Page St. Parking will be temporarily restricted when permanent striping for parking "T"s is installed

Page St to Burbank St:

  • No Parking in both directions
  • Four lanes of traffic on Central have been reduced to a single lane in each direction on the north side of the street - be alert to the new striping and traffic conditions

Burbank St to Sherman St:

  • Parking is permitted on both sides of the street

Other Reminders:

  • Residents living within the construction "no parking" area will have access to their driveways but cannot park on Central Ave.
  • On-street parking is available on adjacent neighborhood streets
  • After paving, there will be one lane of travel in each direction and a center-running two-way-left turn lane
  • When the project is complete, parking will be restored on the north side of the street. The south side of the street will be a curb-protected two-way cycle track

About the Central Ave Project

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 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. It is constructing roundabouts at Main/Pacific/Central, Third/Taylor/Central, Fourth/Ballena/Central. Roundabouts reduce the types of crashes where people are seriously hurt or killed by up to 78 percent when compared to signalized intersections, per federal data.

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:

 

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.
