Innovation of the Month:
Online Resources to Make Every Day Count
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.
- Federal-Aid Essentials features how-to-videos for local agencies on Federal-Aid Highway Program topics, such as steps to successful project delivery and a consultant services overview.
- 3-D Engineered Models covers surveying, design, construction, post-construction, training and resources and includes a link to the 3-D Engineered Models Technical Support Services Center.
- Intelligent Compaction is a one-stop shop with details on fundamentals, reports, workshops, projects and specifications, plus a link to the Intelligent Compaction Technical Support Services Center.
- Slide-In Bridge Construction includes tips on design, construction and contracting and a webinar schedule. It also has a link to the Slide-In Bridge Construction Technical Support Services Center.
- Alternative Contracting Methods Library offers online access to information on deploying design-build, construction manager/general contractor and alternative technical concepts, such as procurement strategies and instruction manuals.
- High-Friction Roads provides information about high-friction surface treatments, including “HFS 101,” demonstration projects, specifications and a library of articles, papers, reports and online resources.
Ohio County Tries Bridge Slide
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.
Rhode Island Accelerates Bridge Job With SPMTs
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.
Training Focuses on Adaptive Signal Control
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.
Work Progresses on Washington Road Repair
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.
