Connected Corridors Program and the I-210 Pilot

Connected Corridors

Statewide program looking at all opportunities

to move people and goods in the most efficient

manner

Focused on transportation corridors in order to

ensure the greatest gains in operational

performance.

Includes freeways, arterials, transit, parking,

travel demand strategies, agency collaboration,

and more

I-210 Pilot

In the San Gabriel Valley – northeast of LA – is

the first Connected Corridors deployment. The

Pilot started approximately four years ago.

I-210 Pilot: Progress So Far

Successfully completed the planning phase

Project Charter signed in June 2015

Concept of Operations agreed upon

Other Systems Engineering documents available as templates

Creation of a new organization at Caltrans focused on TSM&O and performance. Creation of Corridor Manager position.

Funding

$20M in SHOPP funds secured for freeway improvements; completion in 2017

$6M in Metro 2015 Call for Projects funding. Entire process managed by Caltrans with input from cities and County. Completion 2018.

Currently in the requirements and high level design phase

Requirements document in approval process

High level design started
