Construction of New Cross-Alameda Trail Section Began Monday

Construction began Monday on the Cross Alameda Trail (CAT) between Main Street and Constitution Way, along Ralph Appezzato Memorial Parkway (RAMP) and Atlantic Avenue. This long-awaited 0.9-mile segment of the planned four-mile cross-town bicycling and walking corridor is expected to be built by September 2019. 

When complete, the trail will directly connect to the recently opened Jean Sweeney Open Space Park segment of CAT, creating 1.5 continuous miles of separated walking and bicycling trails. By 2020, the final western segment, being built as part of the Site A development at Alameda Point, will connect all users to the new Seaplane Lagoon Ferry Terminal. 

Project Overview

This piece of CAT will provide separate bicycling, walking and jogging trails within the old Alameda Belt Line railroad right-of-way along RAMP, plus a two-way protected bikeway on the south side of Atlantic between Webster Street and Constitution, next to the existing sidewalk. The new facilities will create safe, protected places for people to walk and bike, mostly where none previously existed. 

The project will also feature a landscaped plaza with seating and bicycle racks and lockers at Webster and RAMP. To facilitate safe crossings, significant traffic signal, striping and hardscape improvements will be installed at Webster and RAMP, and Constitution and Atlantic. 

A new mid-block crossing with a flashing beacon will be installed on Atlantic, between Webster and Constitution. Finally, complete remediation of the contaminated soil conditions of the old railroad right-of-way will be done.

While the overall CAT has been envisioned since at least 1991, this latest segment from Main to Constitution has been in development since 2014, when several community meetings were held to develop a concept plan. 

In 2015, the Transportation Commission and Planning Board approved the preliminary design for the Main to Webster segment. The concept design for the one-block segment along Atlantic was subsequently approved by the Transportation Commission and City Council in 2017.  

Once completed, the four-mile CAT will connect the west side of the Island to the east, from the Seaplane Lagoon Ferry Terminal at Alameda Point to the Miller-Sweeney (Fruitvale) Bridge. The segments to the east, along Clement Avenue, are mostly funded and in various planning stages.

Construction will take place between now and September in phased steps. During construction, the public will be required to 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 access to the construction site. 

The city will publish regular updates with forecasts of upcoming construction, along with project manager contact information, at the project webpage, www.alameda
