Cross Alameda Trail: Main Street to Constitution Way


As of August 2020, the project is complete except for some remaining work to be done on the traffic signals at the intersections of Webster St/Atlantic Ave and Constitution Way/Atlantic Ave to facilitate bicycle and pedestrian crossings, including adding bicycle signals and no-right-on-right prohibitions. This work will be completed by the end of 2021.  

The City of Alameda’s Cross Alameda Trail (CAT) is envisioned as a premiere cross-town, low-stress four-mile bicycling and walking corridor that will connect the west side of the island to the east, from the Seaplane Lagoon at Alameda Point to the Miller-Sweeney (Fruitvale) Bridge. The CAT is being built in segments, with many segment in the design or construction phase, and some completed. The Jean Sweeney Park segment (0.6 miles) between Constitution Way and Sherman Street was opened in December 2018.

This web page is dedicated to the Cross Alameda Trail segment between Main Street and Constitution Way. While the 0.9 mile segment will be constructed as one project, it was originally developed as two projects, with distinct timelines: (1) Main Street to Webster Street along Ralph Appezzato Memorial Parkway (RAMP) in an abandoned railroad right-of-way; and (2) a short block between Webster Street and Constitution Way along Atlantic Avenue, which will connect the RAMP segment to the Jean Sweeney segment. 

1) Ralph Appezzato Memorial Parkway (Main Street to Webster Street) Segment

Construct separate walking and bicycling paths plus a decomposed granite jogging path, in the City-owned abandoned railroad right-of-way. This approximately 70-foot wide right-of-way sits immediately to the south of RAMP, adjacent to apartment complexes, schools, several businesses and a Boys and Girls Club. This segment will have the following additional features:

  • Connector trails to two intersecting streets: Fifth Street and West Campus Drive;
  • Pedestrian, bicycle and ADA improvements as well as signage at the intersecting streets;
  • New plazas at either end - Main Street and Webster Street – with hardscape and landscape features; 
  • Landscaping with trees and shrubs; and
  • Traffic signal modifications at 5th Street.

2) Atlantic Avenue (Webster Street to Constitution Way) Segment

Construct separated two-way bicycle lanes on the south side of this short urban block, at street-grade.  This CAT section  includes  significant  improvements  to  the  two intersections, which are among the busiest in the City, to facilitate safe pedestrian and bicycle crossings. The project includes signal modifications, plus the installation of a new mid-block crossing with a flashing beacon, and the creation of a new bus stop platform.
