The existing timber bridge crossing Deep Creek on Christensen Road in Spokane County will be replaced with a pre-cast, pre-stressed, concrete girder bridge spanning approximately 98 feet. BAI completed the geotechnical study that required drilling and sampling, performing two electronic cone penetrometer tests with pore pressure measurement, and laboratory testing on representative soil parameters. BAI completed the geotechnical recommendations for design of earth work, pile foundations, abutment walls, drainage, and pavements.
