CMIA Projects

The Highway Safety, Traffic Reduction, Air Quality, and Port Security Bond Act of 2006, approved by the voters as Proposition 1B on November 7, 2006, includes a program of funding from $4.5 billion to be deposited in the Corridor Mobility Improvement Account (CMIA). The CMIA presents a unique opportunity for the state’s transportation community to provide demonstrable congestion relief, enhanced mobility, improved safety, and stronger connectivity to benefit traveling Californians.
