to the City’s roadways is a high priority for the Los
Angeles Department of Transportation. The Department designs
improvements that optimize the flow of traffic or make streets
safer for motorists and pedestrians.
The Department is proud to inform the public
of the status of projects that enhance motorist and pedestrian
activities in the City.
Carpool Lanes on 405 Freeway between 10 and 90 Freeways:
This $167 million project will construct northbound
and southbound high occupancy vehicle lanes on a 4.1-mile
segment of the 405 freeway. This project will widen freeways
and 12 bridges, relocate ramps, rebuild local streets and
the Palms Boulevard over-crossing, and construct auxiliary
lanes and sound walls. Completion date: Winter 2009.
Carpool Lanes on 405 Freeway between 10 and 101 Freeways:
This $950 million project will complete the 405 freeway high
occupancy vehicle lane system by constructing a northbound
HOV lane between the 10 and 101 freeways. The project will
provide five mixed-flow freeway lanes in each direction, reconfigured
interchanges, widened and/or replaced bridges, 12 sound walls
and about 45 retaining walls. Start date: Summer 2009. Completion
date: Fall 2013.
Closure and Widening of Sepulveda: The $46.7 million
Gap Closure and Sepulveda Boulevard Widening Project has brought
congestion relief to the 101 and 405 freeway interchange.
The project constructed a tunnel under the freeway connector,
separate on-ramps for the 405 and 101 freeways and a bypass
to access the freeway via Dickens Street. The project extended
the 405 freeway’s northbound carpool lane by widening
the freeway and 101 freeway connector. A special southbound
lane was also built on Sepulveda Boulevard to provide access
to the freeway.
• Reversible Lane on Sepulveda: LADOT
engineers plan to implement a reversible lane on Sepulveda
Boulevard during rush hours. The lane – running through
the Mulholland Tunnel –- will alleviate traffic congestion.
The project will also widen intersections of Sepulveda at
• Transit Priority System:
LADOT and Metro have implemented a system that uses advanced
technology to give Metro Rapid buses traffic signal priority
along Metro Rapid corridors and the Metro Orange Line route.
The project, which cost $30 million and debuted in July 2000,
has gained nationwide attention for the significant improvement
it made to these Metro services. By the end of 2008, the system
will have improved 1,150 intersections in 26 transit corridors.
• Fire Preemption System: LADOT and
the Los Angeles Fire Department have developed a system to
reduce fire emergency response times and improve public safety.
Using LADOT’s Transit Priority System infrastructure,
the system gives green traffic lights to emergency vehicles
on a number of streets within the City. The first FPS route
of this $450,000 project will be activated in February 2008
on Broadway and all 26 Metro Rapid routes will be configured
by July 2009.
Main and Spring Streets Median Island:
A raised median island with trees and dome lighting will be
installed at the intersection of Main, Spring and Ninth streets
to enhance bus operations, improve safety and beautify the
Downtown Fashion District. Construction of the $800,000 project,
which is part of the Main and Spring Streets Bus Lanes Project
and funded by Metro, will be completed by June 2008.
• “Pedestrian” Signal Crosswalks:
LADOT is actively installing special pedestrian crosswalks
at pedestrian thoroughfares throughout the City. The crosswalk's
flashing overhead lights are activated with the push of a
button. The lights continue to flash as pedestrians cross
