Boxer toured the Magnolia Avenue Grade Separation project, which is a railroad bridge and road realignment that will ease congestion.
She said it's the type of project the government should be investing in for several reasons.
"If we want to find a way, a bipartisan way, to jump start this economy, create jobs, by the way improve air quality by reducing traffic congestion, and improving safety, a project like this is the name of the game," said Boxer (D-Calif.).
Boxer has proposed a bill to reauthorize the nation's surface transportation projects for the next two years. The current authorization expires at the end of March.
Her office said the bill would sustain nearly two million jobs and create up to a million more.
