Ayear after shifting bridge bents halted work on the $217-million U.S. Route 20 project near Oregon’s coast, engineers are hoping for rain and a solution.

While over 50% of the new 6.5-mile bypass is complete, four bridges up to 1,100 ft long sit partially constructed. Lateral load from adjacent fill and subsurface ground pressure may have caused two of the 20 bents on the 10-bridge project to shift as much as two inches. Since that discovery in February 2010, crews have been collecting data.
The growing need to collect, store and analyze the huge volumes of data collected from infrastructure project stakeholders is generating a new growth area for construction-sector firms, IT vendors and professionals.
