Michael Baker to Design I-90 Interchange Improvement Project Using Accelerated Bridge Construction
PITTSBURGH—Michael Baker International, a global leader in engineering, planning and consulting services, is playing a critical role in improvements to a seven-mile stretch of I-90 in Erie County, Pa., part of the longest interstate highway in the nation. The Pennsylvania Department of Transportation selected the firm to develop preliminary engineering, environmental, geotechnical and final design plans for the project, which is aimed at increasing safety and efficiency for the 20,000 vehicles that use the roadway daily.
“Michael Baker experts will focus on the reconstruction of two interchanges along this section of I-90 that date to the late 1950s,” said Greg Cerminara, vice president in the transportation practice for Michael Baker’s Pittsburgh office. “Our solution raises the new interchange bridges that span over I-90 so they comply with current state law and can accommodate the significant truck traffic in the area.”
Michael Baker’s approach proposes the use of innovative Accelerated Bridge Construction at the interchanges. This technique enables the current structure to remain open to traffic while crews build the new bridge adjacent to the old one. This approach is intended to enhance safety for both workers and motorists by reducing onsite construction time and minimizing disruptions to traffic.
The plan also includes intersection improvements designed to promote efficient traffic flow and minimize delays for motorists.
The project is expected to be complete by 2020.
