Transportation officials are convinced that the new era of safety devices will be key influencers on reducing the number of fatalities at highway construction sites. The new device, a highway speed bump, has been announced as part of the National Work Zone Awareness Week. The device, a portable rubber rumble strip, has been designed so drivers will get a distinctive rough surface that will eventually get their attention and will became aware of the construction site they are approaching. The rubber strip will be deployed in traffic lanes that are to be gradually closed off at construction sites. The safety device is only about an inch high so they will not create hazards to drivers and smooth enough to be able to switch lanes safely. The rumble strips will be deployed with new barrels topped with flashing, self-synchronizing flashing LED lights. There were 2,749 accidents in construction zones statewide last year, down from the 10-year high of 3,651 in 2011.

The Milton-Madison Bride project is achieving a major milestone today. Walsh Construction Company who is in charge to build the new bridge, has started the process of sliding the bridge into place, the longer bridge ever slide into place in North America. The bridge will be moved 55 feet laterally onto refurbished piers and the new 40-foot-wide bridge includes two 12-foot lanes and 8-foot shoulders -- twice as wide as the original bridge. The slide of the 2,428-foot truss (nearly a half mile) will be historic. The bridge will be moved by hydraulic jacks, each one of them about two feet in diameter. These jacks will be moving the bridge about 20 inches per pull, and the bridge will be moved a total of 55 feet to reach its final destination. Because there will be many stops along the way, the process will take most of the day. Once the slide is complete, it will take up to a week to complete the road connections to the bridge.

Finally the $1 billion California high speed rail will get started. The 29 mile rail project will see its first major sign of construction now that the group who won the bid is starting a 2,000 feet viaduct over highway 145 and Raymond Road. The test piling will start in May and shortly after the contractor will start building the massive structure. The builder will also start a new bridge over the San Joaquin River, elevated tracks at the north and south ends of Fresno; a tunnel under Belmont Avenue and Highway 180, and a dozen street or road over- and underpasses. This portion of the project should be completed by 2017.
However the project has been under fire as legal battles are making this project even more challenging. The project is now on a difficult position that could eventually run out of money if this issues don't get resolved fast.

OSHA has announced that a new regulation is being proposed to amend the existing the current ruling for workers performing electric-power generation, transmission and distribution work. The original standard published in 1972 will be addressing constant and new changes on electric power lines and to create a more consistent version of it. The new version will include changes on how contract employees can share safety-related information with each other and with employees. It will also release updated information on fall protection for employees working from aerial lifts and on overhead line structures, as well as redefine standards on how the approach-distance requirements used to protect workers from energized equipment. The final rule also adds new requirements to protect workers from electric arcs, according to OSHA. 'The new standard for electrical protective equipment applies to all construction work and replaces the existing construction standard, which was based on out-of-date information, with a set of performance-oriented requirements consistent with the latest revisions of the relevant consensus standards,' OSHA said. The new standards address the safe use and care of electrical protective equipment, including new requirements that equipment made of materials other than rubber provide adequate protection from electrical hazards.
