How You Can Help Create MOMENTUM

Prop 400

Development of the region’s new Regional Transportation Plan will rely heavily on the needs and priorities of the traveling public. One way to ensure you can get to the places you need to go in the years ahead is to make your voice heard. The best way to do that is by visiting the plan website at

“Our region is growing. Fast,” points out the website under the heading, Why it matters. “Growth means more strain on our transportation system, slowing down our commutes and our everyday lives. Intentional and thoughtful transportation planning means we can spend our time on the things that matter.”

The site, which will go live in August, asks users to join the conversation by sharing their experiences, ideas, and priorities. Users can provide input on any transportation topic, including access to our transportation system, bicycle and pedestrian infrastructure, bus service, freeway and roadway improvements, high capacity transit (light rail, commuter rail, streetcar, bus rapid transit), new transportation technologies and innovations, and safety.

More than 10,000 Valley residents provided early input into the planning process by participating in a “values survey” in which they were asked what was most important about this community and moving around the region. Those responses were used to lay the framework for the planning process.

For more examples of how the residents of the region have shaped the regional transportation system, you can jump back to 1985, when voters passed Proposition 300. That investment continued through Proposition 400 in 2004. Combined, the Propositions delivered Loops 101, 202, and 303; light rail; arterial street investments; and contributions to a growing multimodal network—a total investment of over $12 billion.
