District and HQ collaborate to expedite I-84 bridge repair

Earlier last week, crews in District 4 worked with the Headquarters Bridge section to repair damaged bridge joints on Interstate 84 near Glenns Ferry. It was most likely damaged due to the lower position of that joint compared to the rest of bridge deck and the resulting impact and vibration of passing vehicles. You can hear it on this video.

During a routine inspection, HQ Bridge Inspector Toby Griffin found that a portion of the bridge joint was missing, and another section was broken and loose.

“I was in the area doing a routine inspection of railroad structures below when I heard loud clanking sounds coming from the bridge deck above,” said Griffin. “This was not normal, so I investigated further and discovered the broken joint.”

Toby texted a photo of the damage to his supervisor, Dan Gorley, who quickly reached out to D4 Maintenance Coordinator Shawn Webb.

After discussing the situation, it was determined that a lane closure would ensure the safety of motorists driving westbound on the interstate. Despite it being after normal working hours, crews were onsite and implementing traffic control within the hour, while district and headquarter personnel worked into the evening to develop an emergency repair plan.

The following morning, crews were dispatched to the bridge deck to begin work. Repairs included removal of broken bolts, rethreading of damaged base plates, and welding and re-installment of the broken finger joint section.

“This was a great example of ITD personnel working together in an efficient and collaborative effort to ensure successful execution of one of the department’s key mission points – safety,” said Webb. “Four separate crews came together quickly to work as one to find a viable solution that allowed us to reopen the roadway within 24 hours of the initial discovery.”

The Bliss Foreman area crew, the D4 Bridge crew, the D4 Welder/Machinist, and personnel from HQ’s Bridge Inspection crew all participated in repair efforts of the broken bridge joint.

Planning is underway for development of a strategy to address the joints located on the westbound and eastbound bridges at this location. Webb stated that “the goal is to have a more permanent solution regarding this issue in the near future.”

Emerald Street Connector Overpass opens Saturday

Crews wrap up the repavement of the Emerald St. overpass along I-184

BOISE – Bridge preservation work on the Emerald Street overpass of I-184 (the Connector) between Cole Road and Curtis Road, is complete. The bridge reopens to all traffic beginning Saturday morning (May 19).

Preservation work on additional Treasure Valley bridges will continue this summer at the following locations:

I-84, Meridian Road Interchange
I-84, Broadway Avenue Interchange
I-84, Cole-Overland Interchange
I-84, Gowen Road Interchange
Broadway Avenue, Boise River Bridge

Unlike at Emerald, remaining work will not require full closures and most work will be completed at night. Motorists can expect lane reductions and reduced speeds.

“Bridge preservation work is intended to strengthen the bridge surfaces and extend the life of the pavement, reducing the need for additional maintenance at a later date,” said Crystal Grasmick, ITD Project Manager. “We appreciate the traveling public’s patience as we work through these important improvements.”

Cannon Builders, Inc. is the contractor on this $2.7 million project. For up-to-date traffic impact information, visit 511.idaho.gov.

Bridge replacements and pavement rehabilitation to begin on U.S. 95 near Parma in mid-April

Work will occur at the junction of U.S. 95 and U.S. 20/26 and include the reconstruction of the Union Pacific Railroad overpass, Sand Hollow Creek Bridge and nearby pavement rehabilitation.

*The project is scheduled to be complete this winter.

*A posted detour will be in place during the project. A separate truck detour will also be posted. The speed limited will be reduced to 45 mph in the work zone. The speed limit will be reduced to 45 mph on U.S. 20/26 when shoulder or median work is occurring. Flaggers will assist motorists through the work zone during different phases of the project.

*Most work will occur Monday through Friday, and some Saturdays.

Motorists are encouraged to check 511.idaho.gov for construction updates and detour information.

With nearly 45 projects scheduled across the region this year, please plan ahead, slow down, and give yourself enough time when traveling through each work zone.

Work on East Kooskia Bridge finishes early

With crews working long hours and the weekend, work on the East Kooskia Bridge finished ahead of time and the bridge opened to travel Feb. 28, at least a week early. The improvements allowed ITD to boost the bridge’s load-carrying capacity from 6,000 lb. Gross Vehicle Weight (GVW) to 16-20 tons GVW, depending on axles.

It’s just the latest example of ITD providing great service to our customers, the users of the transportation system.

Work on the 82-year-old bridge began Feb. 20 and finished by the end of the month. Prior to repairs, the bridge’s condition allowed only for lightweight passenger vehicles.

The 481-foot-long, steel-truss bridge is on the Idaho 13 Business Route, just off U.S. 12. It is a single-lane structure at milepost 75.2 built in 1935.
