Devil's Slide Repairs


On April 2, 2006, Highway 1 at Devil's Slide was closed. Once again, this geologically unstable section of coastline slid a little closer to the ocean. Less than 24 hours after the road was closed, massive boulders came crashing down from 300 feet above the roadway. In the video, a senior Caltrans geologist explains why this section of road continues to fail and describes how Caltrans will fix the problem. Learn a little about the history of Devil's Slide and how the latest repair compares to the one in 1995 when the road was closed for about 6 months.
Sonoma 101 Groundbreaking


Ground breaking ceremony for Sonoma 101 HOV widening project was held on April 4, 2006. This major construction project is to widen US 101 from four to six lanes between Route 12 and Steele Lane in Santa Rosa. The new lanes will be northbound and southbound carpool lanes, which will add capacity and encourage ridesharing in this congested corridor.
Steel Span Lift


The first of two steel transition spans was lifted into place during an around the clock thirty six hour operation. At 1700 tons, this was one of the largest construction lifts in California history. These steel transition spans will connect the concrete Skyway with the steel Self Anchored Suspension Span of the new San Francisco Oakland Bay Bridge East Span.
Pier Tables


Caltrans is retiring the historic 1927 Carquinez Bridge since it was replaced by state of the art, Alfred Zampa Memorial Bridge in 2003. This video celebrates the building of the original Carquinez Bridge, paying tribute to the first bridge to span the strait and its role in Bay Area history..
ITS Rocks


In November 2005, Caltrans had the honor of co-hosting the World Congress on Intelligent Transport Systems, here in San Francisco at the Moscone Convention Center. The ITS World Congress also offered the Innovative Mobility Showcase at SBC park that demonstrated the latest ITS technologies at work - live, on a simulated State Highway System. Following video captures the events & technologies highlighted at the ITS World Congress.
Pier Foundations


The building of the East Span of the New Bay Bridge begins with the construction of the foundations in the bay waters and below. The video captures how these steps are accomplished: building coffer dams, placing footing boxes, pile driving, placing rebar cages in the steel piles, and finally pouring the concrete.
Pier Tables


The next major process is to build piers and pier tables. The video highlights the following steps: fabrication and placing of the pier column rebar cages, steel forms erection, concrete pour for the pier columns, step by step building of the pier table, and lastly the post-tensioning.
Octavia Ribbon Cutting


The Central Freeway was one of the most controversial debates in San Francisco: To build or not to build the damaged freeway through The City. Watch as San Francisco's politicians, transportation experts, and citizens join together in celebrating the opening of The Central Freeway Market St. on and off-ramps, and the beautifully landscaped adjoining Octavia Blvd. .

This project is truly a collaborative effort that would not have been possible without the generous contribution of time, effort and an abundance of positive energy provided by the community of West Oakland, the California Department of Transportation (Caltrans) and the City of Oakland. Enjoy the video and then find time to take a stroll along Mandela Parkway. The pleasure will be yours.
The Devil's Slide Portal


The Devil's Slide project is located on State Route 1 in San Mateo County between the town of Montara to the south and City of Pacifica to the north.

The project will construct approximately 6,500 linear feet of new alignment along State Route 1, consisting of two parallel 4000-foot tunnels, a north portal approach of 1,500 feet that includes parallel bridges measuring 1,000 feel, and a south portal approach of 1,000 feet.
New Benicia Video


Benicia Martinez Bridge is one of the most heavily traveled bridges in the state. An additional bridge span is being constructed adjacent to the existing Benicia Martinez Bridge along I- 680 across the Carquinez Strait. Besides the construction of the new span and improvements of the existing bridge, there are several related projects under construction.This video shows the current status on the new span and other related projects.


This video commemorates California Highway Workers who lost their lives in the line of duty. Highlights of the ceremonies of the three memorial plaques located throughout District 4 as well as several Caltrans employees paying tribute and remembering our coworkers are included in the video.
Carquinez Fireworks


This short film explores the construction of the new Carquinez (Alfred Zampa Memorial) Bridge through exclusive interviews with key television and newspaper reporters as well as community representatives. This short film features time-lapse footage of bridge construction and the largest fireworks show ever on the Carquinez Strait during opening celebration. This 7 minute segment supplements the 35 minute Caltrans documentary "Spanning the Carquinez Strait" with completely new footage. The full documentary is now available on DVD and VHS through the Caltrans Historic Preservation Society at http://www.dot.ca.gov/hq/esc/CHPC/.


In a continuing series of short web videos documenting new carquinez bridge construction in District 4, Bart Ney, the public information officer at the bridge, discusses deck welding and wire wrapping of the main cables.


The two and a half minute web video's purpose is to inform the public on the procedures used by Caltrans and its contractor FCI-Cleveland Bridge on lifting the Carquinez Bridge's deck sections into place. On-camera interviews of Public Information Officer Bart Ney describe the procedure during the historic last day of deck erection, as the last deck section is being lifted into place. Using time-lapse video, District 4's A-V video crew captured a complete deck lift on the north side of the bridge, from the California Maritime Academy. What usually takes 4 hours is compressed into less than 30 seconds. The action includes iron workers at work and personnel using computer assisted strand jacks.


Caltrans has received numerous emails and phone calls regarding the one-inch thick steel plates that have been placed on the upper deck of the Bay Bridge just west of the Yerba Buena Tunnel. Although the plates have been designed to accommodate 50 mile- per-hour traffic, many drivers slow down prior to the plates. The slowing of just a few vehicles on a congested bridge can greatly increase traffic congestion. Many motorists have complained about the increased delays. ==>> MORE


The following video was taken during the first sound attenuation test on the Benicia-Martinez Bridge on July 12, 2002. The video shows the isolation casing, Enduraflex coating and bubble curtain being used in conjunction to reduce the sound levels experienced in the Carquinez Straits during pile driving operations with the Menck 500T hydraulic pile driving hammer.


Californians annually produce 33 million waste tires. Instead of clogging landfills, 70 percent of these are recycled and used in engineering, environmental and consumer projects.

This video outlines the use of recycled tires in this new ramp. You will learn how waste tires are prepared, why they're a viable alternative and the specifications necessary for civil engineering applications like this. ==>> MORE


Caltrans is proud to present you with an new public service announcement (PSA). This video address motorist safety when encountering work zones. We strongly encourage motorists to drive safely at all times, but especially so near work zones where unsafe and irresponsible driving places both the driver and workers in jeopardy. ==>> MORE


In the mid 1990s, The California Department of Transportation produced this classic "Office Drive-Through" public service announcement. It's message remains important today.


The view begins with an overhead still view of the bridge. When the animation begins, the viewer is looking northbound towards Pacifica from the edge of San Pedro Mountain. The camera then swoops to the side to give a profile of the bridge. Video ends with a view from the southbound direction, looking into the incandescently-lighted tunnel bores. ==>> MORE


DO YOU HATE LITTER? So do we. And so does "Evening Magazine" host Mike Rowe. Recently, Mike joined our maintenance crews for a day of litter removal. He could not believe what he found, and neither will you. Watch the entire segment, courtesy KPIX-TV.
