Disclaimer: Information about the Whittier Narrows Dam Safety Modification Project is constantly evolving and subject to change based on project updates from the USACE.

Small sections of Lincoln Avenue and Rosemead Boulevard that run parallel to the immediate project area will be raised approximately 6-feet. The U.S. Army Corps of Engineers (USACE) is not anticipating having to completely shut down the streets throughout the course of the project and will, instead, work on these street modifications in sections by temporarily narrowing the streets, which may cause traffic congestion.
