The project is anticipated to begin on April 30, 2012 and be completed in late June 2012. The project has been funded through Local and Federal Grants. Due to the project's proximity to Mt. SAC, the City has coordinated extensively with Mt. SAC staff to avoid conflicts with Mt. SAC events. In order to minimize impacts of the construction and to maintain access to the Mt.

Alameda Corridor-East Project - COMPLETED

Alameda Corridor-East Project encompasses a distance of 35 miles through the San Gabriel Valley between East Los Angeles and Pomona (generally paralleling the I-10 San Bernardino Freeway and SR-60 Freeway. The project connects the Alameda Corridor and the Ports of Los Angeles and Long Beach to the transcontinental rail network, creating a faster, more efficient method of distributing the expected $314 billion in annual trade.

With the completion of the Alameda Corridor, train traffic through the San Gabriel Valley will increase by as much as 160 percent by the year 2020. The goal of the $950 million Alameda Corridor East (ACE) Project is to mitigate the effects of increased traffic along a 35-mile freight rail corridor through the San Gabriel Valley from East Los Angeles to Pomona. The ACE Project includes transportation safety improvement projects at 39 grade crossings located throughout the San Gabriel Valley. 

The project is designed to improve mobility and safety by constructing grade separations at 20 rail crossings along the corridor including the following streets that boarder the City of Walnut; Nogales Street, and Fairway Drive. 

The grade separation of Nogales Street under the railroad tracks and Valley Boulevard was completed on schedule, opening to traffic on August 28, 2005. The grade separation of Fairway Drive is still pending due to funding, project proposed for 2007. 

Resources for the ACE project are provided by Federal, State, Regional, Union Pacific Railroad, and Metropolitan Transportation Authority (MTA).

Project benefits for the City of Walnut include safety upgrades at the Brea Canyon Road rail crossings along the ACE corridor. Safety upgrade includes, new traffic and train signage, re-striping of streets, updated signal preemption, measures to eliminate gate drive-arounds, minor roadway widening, installation of active warning devices, new pedestrian sidewalks and safety protection, re-grading and repair of vehicle crossings, and other measures designed to improve traffic flow or enhance safety. Other project benefits include reduced air and noise pollution for the City of Walnut.

Brea Canyon Road may have some minor interruptions due to construction that is planned to take place August 2006 through January 2008.

Overall the ACE Project completion is slated for 2008. For questions, comments or would like the latest construction information, please call the project helpline, 888-ACE-1426, or visit the website at:
