The Every Day Counts website is the go-to source for information on all of the innovative technologies and practices the Federal Highway Administration is promoting through the EDC initiative.
If you're looking for more details on specific innovations, a number of websites may have the information you need:
Ohio's Wyandot County is using a bridge slide to rehabilitate Indian Mill Bridge on County Road 47 over the Sandusky River. The contractor devised the innovative solution to replace the bridge, a circa 1913 Pratt through truss. Removal and reinstallation of the historic bridge are being done by sliding the bridge across a track supported on a smaller modular panel bridge inserted inside the bridge. After the bridge is disassembled, the main steel bridge members will be cleaned and hot-dip galvanized off-site and then replaced.
Accelerated bridge construction techniques are helping the Rhode Island Department of Transportation replace the Barton Corner Bridge. The bridge carries four lanes of I-95 plus two auxiliary lanes at a busy interchange in the Warwick area. The agency is building two halves of the bridge on land next to the overpass and will move them into place with self-propelled modular transporters. This approach will enable the Rhode Island DOT to minimize the project's impact on interstate traffic and build the bridge much faster than with conventional methods.
The Tennessee Department of Transportation and FHWA hosted a course on “Systems Engineering for Signal Systems Including Adaptive Control.” Attendees at the June 18 and 19 event represented a cross-section of Tennessee's local, state, federal and academic communities. Participants learned about the technical details, costs and benefits of deploying adaptive signal control technology. Tennessee has already used the technology in Chattanooga and is evaluating future deployments in Mount Juliet, Franklin and other cities.
Design work is proceeding on the design-build project to reconstruct a section of State Route 530 in North Snohomish County, Washington, damaged in a March landslide. Construction is expected to start in mid-July, starting on the east side of the slide area and moving west. Substantial completion of the new alignment is expected in early October. The designer-builder is now working on water management and surveying. The road opened to two-way traffic through the landslide area on June 20 after initial repairs were completed three days early.
