The U.S. Dept. of Transportation awarded $1.5 billion in grants through the American Recovery and Reinvestment Act to 51 projects in 41 states and the District of Columbia on Feb. 17, underscoring the Obama administration’s transportation priorities. The Transportation Investment Generating Economic Recovery funds, known as TIGER grants, target projects that USDOT identified as being “major national and regional transportation projects that are in many cases difficult to pursue through other government funding programs.” Although a mix of transportation modes received grants that range from $3.15 million to $105 million, freight-rail and transit projects received the largest individual grants.

A massive highway renovation is unfolding only minutes away from Vancouver’s Winter Olympics, and the centerpiece will be a new cable-stayed bridge crossing the Fraser River from Surrey to Coquitlam.

At 1.2 miles in length including approaches, the bridge will be one of the longest of its kind in North America. Part of a 22.9-mi, $2.33-billion overhaul of Highway 1, the principal corridor in the greater Vancouver area, the project is designed to ease congestion, especially on the existing Port Mann Bridge.

Lynchburg, Va.-based Babcock & Wilcox will work with FirstEnergy, the Tennessee Valley Authority and Oglethorpe Power to place its small-scale, 125-MW modular nuclear unit, called mPower, into operation by 2020, says Chris Mowry, CEO of B&W Modular Nuclear Energy LLC. The company and the utilities, which announced their consortium on Feb. 17, will work with the U.S. Nuclear Regulatory Commission to modify the licensing process for the modular reactors. None of the companies working with B&W has agreed to buy its reactor because “we really need to get deeper insight on this thing, where and how exactly to deploy,” says

The long-awaited nuclear renaissance appears to be closer to reality. The Obama administration continues to send strong signals of support for nuclear power as part of the nation’s “clean-energy” future. On Feb. 16, the administration announced the first-ever $8.5 billion loan guarantee for a new nuclear plant and said it had introduced plans to triple the amount of nuclear loan guarantees in the fiscal 2011 budget.

As spring approaches, officials from Minnesota to New Orleans are eyeing Mississippi River levees—already lapped by higher-than-normal water levels—and bracing for likely floods.

U.S. Environmental Protection Agency Administrator Lisa Jackson fleshed out details of the administration’s five-year, $2.2-billion Great Lakes Restoration Initiative Action plan at a Feb. 21 news conference at the National Governors’ Association’s winter meeting in Washington. The plan, which covers fiscal years 2010-2014, was developed by 16 federal agencies. It calls for cleaning up some of the most heavily polluted hot spots, including remediation of 9.4 million cubic yards of contaminated sediment; restoring wetlands and other habitats; establishing total maximum daily loads for phosphorus; and taking steps to keep invasive species such as Asian carp out of the lakes.

The United Nations now estimates that 3 million Haitians—a third of the population—were “badly affected” by the magnitude-7 earthquake that ravaged the island nation on Jan. 12. Providing shelter, sanitation and preventing cholera in Port-au-Prince are critical challenges, but so are food shortages in rural areas. An estimated 500,000 former residents of the badly damaged capital have migrated to the countryside.

Engineers are finalizing design for a 17-mile-long pipeline that will deliver methane gas from a landfill in Muskego, Wis., to fuel a wastewater treatment plant in Milwaukee. The pipeline is the first step in an $80-million investment that will save the Milwaukee Metropolitan Sewerage District (MMSD) at least $148 million over the next 20 years by enabling its Jones Island plant to generate its own heat and electricity by burning landfill-generated methane instead of natural gas. In addition to saving money, the plant will also cut greenhouse-gas emissions by 500,000 tons a year. MMSD tentatively plans to seek bids from

Design and construction of Minneapolis’s Target Field, a $545-million ballpark for baseball’s Minnesota Twins, was like stuffing 12 lb of potatoes into an 8-lb bag. The eight-acre site not only was hemmed in on all sides by roads and rails, it really needed 12 acres to comfortably accommodate the program for a 40,000-seat ballpark. Because the neighbors were so close, there was no lay-down area or viable crane path outside the bowl’s footprint. Thus, the ballpark had to be constructed from the inside out, which builders consider far from ideal. Slide Show Photo: Mortenson Construction The many restrictions, including up
