Caltrans Upgrades $39.2M Manzanar/Independence By Erik Pisor CEG CORRESPONDENT
The Manzanar project is slated for a fall 2010 completion, while the Blackrock project wrapped up, on schedule, in early August.
For Southern California skiers, snowboarders and mountain bikers U.S. Highway 395 serves as the main route to and from Mammoth Mountain, the tallest ski resort in the state. Because a significant portion of Highway 395 has always been a two-lane highway with no median separation, head-on collisions often occur due to passing attempts. This summer steps were taken to change that, as two separate construction projects — focused on expanding and upgrading a combined 26 mi. (41.8 km) of Highway 395 — were underway. The $28.2 million Blackrock Four-Lane Project focused on upgrading and expanding 14 mi. (22.5 km) of two-lane highway, in between the cities of Independence and Big Pine, into a four-lane expressway. The $39.2 million Manzanar/Independence
Four-Lane Project includes similar upgrading work along 12 mi. (19 km) of Highway 395, and also involves the construction of a fourlane, all-paved road within the city of Independence. The Manzanar project is slated for a fall 2010 completion, while the Blackrock project wrapped up, on schedule, in early August, according to Susan Lent, public information officer of Caltrans District 9. Located between the towns of Independence and Big Pine, the Blackrock project began in October 2007. The project’s first stage involved the construction of two new lanes west of the existing lanes. “Our biggest challenge on this job was rock,” said Mark Hegbloom, project manager for general contactor Skanska USA Civil West. Hegbloom explained that a 14H blade and 623-finish scraper pulled up a significant see MANZANAR page 6
Bids Opened on Long-Awaited Caldecott Tunnel Extension Bids have opened to build the fourth bore of the Caldecott Tunnel, a long-awaited project that will remove a bottleneck on busy Route 24 between Oakland and central Contra Costa County, in California. The Caldecott Tunnel project will deliver congestion relief for the 160,000 motorists who travel the corridor daily while also delivering significant economic benefits to the region, even before its ribbon-cutting. Four bids were opened and the California Department of Transportation (Caltrans) will review the apparent low bid, by Tutor-Saliba Corporation of Sylmar, Calif., to ensure it meets all contract requirements.
“Today the long-awaited Caldecott Tunnel project took a big step forward toward becoming a reality, made possible through state and local dollars and our actions to secure federal funds,” said Gov. Arnold Schwarzenegger. “This project will reduce local traffic congestion while creating nearly 6,000 jobs for California — and is a solid investment in the future of the Bay Area’s transportation infrastructure.” Financing for the project, estimated at $420 million, comes from state, local and federal funds. This includes $11 million from Proposition 1B, the transportation bond championed by the governor and approved
by voters in 2006, as well as the $197.7 million the state secured from the federal government through the American Recovery and Reinvestment Act (Recovery Act). This project is scheduled to begin in late 2009/early 2010. Contractor bids include the cost of completing work as well as the number of days required before the tunnel is opened to traffic. The project has set a goal of hiring at least three percent of its contracted amount for underutilized, disadvantaged business enterprises. The project is a partnership between Caltrans, the Contra Costa Transportation Authority and the Alameda County
Congestion Management Agency. Work crews will build a two-lane, 0.66 mi. (1.1 km) long tunnel north of the existing three bores. Upon completion, the new bore and the existing northernmost bore will be permanently dedicated to westbound traffic, while the two southernmost bores will carry eastbound traffic. The new configuration will eliminate the current situation where workers at the tunnel must reverse the traffic direction in the center bore twice a day to accommodate the morning and evening commutes and the consistently shifting traffic patterns on busy weekends.
