National Work Zone Awareness Week, April 7-11 2008


April 7-11 is National Workzone Awareness Week (NWZAW) which draws attention to the hazards roadway construction crews face from motorists not heeding safety warnings. For 2006—the last year for which data is available—more than 1,000 died in work zones. Figures for 2007 will be released by the National Work Zone Safety Information Clearinghouse later this year. Motorists are also at risk for not following work zone safety precautions. They may face damage to their vehicles, injuries, and loss of life. For 2006, 614 motorists died in work zone crashes.

Below are a few items to think about the next time you’re driving through a workzone taken from a Caltrans fact sheet. More after the break (sorry for the “Duh” ones, but I didn’t write them). As someone who occasionally works on the road and knows many more people who do, please, please remember to slow down!

  • Most injuries and deaths in the Cone Zone are from rear-end collisions.
  • If you slow from 65 to 55 mph for one mile, you only lose 10 seconds on your travel time.
  • The first cause of death for people aged 16 to 20 is car crashes. Even if you don’t lose your life causing a car crash, it could still cost you your license or a heavy fine.
  • If a car’s speed is doubled, the stopping distance is doubled twice over. For example, if a car traveling at 30 mph requires 100 feet to stop, the same car at 60 mph takes not 200 but 400 feet to stop.
  • At 60 mph, you’re traveling 88 feet per second. A lot can happen in one second, so give yourself plenty of room to stop in case of an emergency.
  • For the 15,000 miles of California highway Caltrans maintains, it must buy 120,000 new cones every year to replace ones run over by careless drivers.

Devil’s Slide Tunnel Construction Kicks Off

On September 17, CALTRANS and Kiewit Pacific held a "tunnel excavation celebration" to kick off the start of tunnel construction on The Devil’s Slide Tunnels project on California State Route 1 (the Pacific Coast Highway) in San Mateo County between the town of Montara to the south and the city of Pacifica to the north. The project involves the creation of a separated two-lane road, one lane in each direction. This road will pass through twin tunnels, over twin bridges and connect with an existing non-separated two-lane road at each end. The new road will be approximately 6,500 feet long, made up of the roughly 4,000-foot twin tunnels, the 1,500-foot north approach road (which includes the 1000-foot parallel bridges), and the 1,000-foot south approach road. Upon completion, the new road will bypass geologically unstable portions of existing Route 1, sections of roadway subject to lengthy closures, high maintenance costs over the years, and risk of permanent failure. Thanks for the heads up. [Read on for more background, photos, maps, and movies!] (Images by CALTRANS)
