Cross Alameda Trail: Main Street to Constitution Way


On February 11, 2019, the City of Alameda began construction of this long-awaited 0.9 mile segment of the Cross Alameda Trail.  Press release

General schedule as of 08/01/19:  Construction activities will take place between February and Late October/Early November 2019.

The majority of the grading for the new trail and landscaped areas between Main and Webster Streets will occur in four phased segments, generally moving from west to east, as shown below: 

  1. Main St to 3rd St: February through May
  2. 3rd St to Poggi St: End of May through June
  3. Poggi St to Webster St: July through August
  4. Main St. at Atlantic Plaza (Hometown Doughnut, Monkey Thai & Whisk Cake Creations): August & September

The section from Webster to Constitution, which includes concrete, electrical, traffic signal & roadway striping improvements only, will take place in September and October.

After the initial grading is complete, the work will focus on completing the construction of the new trail in one continuous piece – fine grading and import of soil and rock to final conditions. The new trail will consist of concrete walkways, decomposed granite and asphalt paving.  New concrete construction work – new sidewalks and curb ramps – will begin in August and go through October. The City will attempt to schedule the locations of the work to minimize impacts to adjacent residents, schools and businesses. Final activities will be installing the new plantings, irrigation systems and site furnishings – such as benches & bike lockers.

All durations are estimates and some delays may occur.

Soil Remediation and Monitoring: 

As part of the soil remediation plan, the Contractor has been importing and stockpiling new soil for the site at a nearby location on Alameda Point since May. The heaviest trucking activity to the site is expected to finish in early August. During these grading activities the site is being electronically monitored for airborne air and dust contaminants, both on-site and off-site. Alerts are automatically issued to the Project Team and Contractor to be immediately resolved if and when County-dictated air quality thresholds are exceeded.

To view any of this project-related air quality (or other compliance) data, please visit: This link, by Alameda County Department of Environmental Health, provides public access to State Water Resources Board’s project-specific ‘GeoTracker’ website, an internet-accessible database system used by State, Regional, and local agencies, to track and archive compliance data – in this case specifically for the CAT/RAMP + Gap Project.  This website provides ready access to a large variety of documents and information, including – but not limited to:

  1. Regulatory Activities and Environmental Data

  2. Site Maps and Environmental Soil Borings

  3. Investigative Reports and Soil Import Approvals

  4. Remedial Action Plans and Risk Assessment Reports

  5. Air/Dust Monitoring Work Plans, Activities, and Alerts

During construction, please:

  • Use the existing sidewalks on the north side of RAMP as temporary construction fencing will be erected on the south side, prohibiting any public or private use of this active construction zone. The fencing will be in place to keep pedestrians out of the active work site, which includes contaminated soil work.

Questions or concerns regarding construction should be directed to:  

  • Construction Manager: Steve Patterson, 510-701-0319,
  • Public Works Project Manager: Jack Dybas, 510-747-7948,
  • Contractor: McGuire and Hester, Brian Thompson, 510-632-7676

The City realizes this construction will have short-term impacts on people living and visiting Alameda. The City and Contractor will work to minimize disruption, as much as possible, to all who use the corridor and will keep neighboring property owners and the community informed. Patience is appreciated, as the City works to complete this major capital improvement project.

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.
