MOT-70 Arlington Road Bridge

Project Details

Ohio Department of Transportation (ODOT), District 7

Brookville, OH


Woolpert provides roadway, bridge, survey, maintenance of traffic, right-of-way and right-of-way acquisition services to ODOT District 7 as part of a general services contract. Woolpert was tasked with the emergency replacement of a damaged structure carrying Peters Pike over Interstate 70 outside of Dayton, Ohio. This fast-track project, a natural part of ODOT’s “Build Bridges Faster, Smarter, Better” program, allowed only 90 days for design; 45 days for ODOT document preparation, advertising and bidding; and 90 days for construction.

In order to complete the project in the accelerated timeframe, Woolpert initiated demolition and right-of-way acquisition concurrently with design.

We also established a secure project website to expedite submittal review. To allow for the shortest construction schedule, Woolpert designed a two-span, transversely post-tensioned composite box bean on a T-type pier with semi-integral abutments atop turn-back MSE walls. We were also able to raise the profile of Peters Pike nearly three feet while keeping the structure depth almost the same, yielding an increased vertical clearance exceeding ODOT’s design minimums.

Woolpert employed innovative technology, including a Riegl LMS-Z360 laser scanner, to prepare intelligent CADD drawings in Microstation and Geopak. After just one-half day of scanning and 12 individual scans, we processed data, aligned scans and developed the CADD drawings and bridge plans. We also used the aligned scans to create 3D models with open mesh and solid surfaces.
