For years, a higher-speed rail route between Chicago and St. Louis "has been a construction season or two away from reality," says Rick Harnish, executive director of the Midwest High Speed Rail Association. Pleasantly surprised by the $8-billion pot created in the final stimulus package for high-speed rail, he says, "Hopefully this will put it over the edge."

High-speed rail is the surprise winner in the $787-billion package, which includes $48 billion for transportation infrastructure. "It was a
Bart Ney gets concerned calls from people just about every day. They see the steel trusses starting to cross San Francisco Bay between Yerba Buena Island to the west and the new 1.2-mile-long precast concrete Skyway to the east, alongside the existing eastern steel truss span of the old Bay Bridge. They wonder why the trusses don’t look at all like the striking self anchored assymetrical suspension span they saw in the renderings. Slide Show Susan Lohwasser / ENR A temporary bridge will take shape this year to carry segments of new self-anchored suspension span until cable arrives. Related Links:
Jack Wilson admits it: He welcomes the rising price of asphalt. It’s not a concrete bias—he is a 40-year contracting veteran who worked impartially with both asphalt and concrete. But now that asphalt milling and repaving is more expensive, he believes the time has finally come for his asphalt overlay invention to gain a wide audience.

With the help of special skids and common soap, an Oregon contractor has replaced two bridges in two weekends as part of a $46-million design-build project for the Oregon Dept. of Transportation. Slayden Construction Group Inc., Stayton, broke ground on the project in June 2007 and wrapped it up in January, replacing a total of five 80-year-old bridges along Highway 38 between the towns of Elkton and Drain.

Bong-Hyun Cho, manager of the immersed tunnel site for the $1.8-billion Busan-Geoje fixed- link project, finally can get some sleep. Six of 18 concrete tunnel elements, 180-m long and 45,000 tonnes, have been towed successfully from a dry dock 35 km away, sunk into the turbulent depths of the Pacific and placed atop specially designed gravel beds with tight tolerances. "If the gravel beds fail, the project fails," he says. "I was so anxious." Slide Show Photo: Halcrow Korea’s 8.2-km-long sea link will connect the mainland to Geoje Island through three islets. After a rocky start with glitches in the
Rail, marine and airport officials are pragmatically waiting for the final version of a stimulus bill. Everyone would like more stimulus project funds, but they would also like policy and programming changes. Such changes could be reflected in attempts to reauthorize the six-year transportation trust fund and the airport improvement program later this year. At a Transportation Research Board session held earlier this month in Washington, D.C., Maryland State Highway Administrator Neil Pedersen said many officials were calling the stimulus request process a “dress rehearsal” for reauthorization.
