Rhode Island’s new $163.7 million, 2,265 ft (690 m) long, four-lane Sakonnet River Bridge sits just south of the existing bridge in Portsmouth/Tiverton. Foundation design and construction challenges make the project noteworthy. The Sakonnet was one of the first major bridge projects in the country to incorporate AASHTO Load and Resistance Factor Design (LRFD) guidelines for foundation design and construction. The Sakonnet River Bridge was an OPA Finalist.

Li, C.Eng, P.Eng. and Brian W. Wilson, C.Eng, P.Eng. An extensive deep mixing ground improve- ment program using the Cutter Soil Mixing technique was designed and constructed in 2013 to support Mechanically Stabilized Earth walls and bulk earthworks for the development of the Kitimat Liquefied Natural Gas (LNG) facility at Bish Cove, British Columbia, Canada. As part of the earthworks required to provide a level grade for a portion of the Kitimat facility, two MSE walls, approx- imately 165 m (541 ft) and 300 m (984 ft) long forming an “L” shape, were proposed.
