UPDATE: Commuter traffic in-town detour – Shoshone railroad closed for repairs May 16-18

SHOSHONE – UPDATE – Commuter motorists will be detoured in-town around the Shoshone railroad construction zone while trucks will be detoured onto to highways.

The Idaho Transportation Department (ITD) asks drivers in the Shoshone area to plan ahead, as a section of U.S. Route 26 at milepost 165.93 will be closed for railroad repair May 16-18.

The crossing will be closed to motorists starting on Tuesday, May 16 at 6 a.m. and will reopen when work is complete by approximately 6 p.m. on Thursday, May 18. To receive the most current traffic updates, call 511 or sign up at 511.idaho.gov.

Crews beginning I-15 Blackfoot bridge repair after overnight road breakup

I-15 road surface breakup

POCATELLO – Idaho Transportaion Department crews are currently working on the northbound bridge of I-15 just north of Blackfoot to repair the road surface following damage that occurred last night. The cause of the problem is still under investigation, but road breakup is common following cycles of warm and cold weather.

Traffic is down to one lane as crews begin repairs on the right lane. Tomorrow traffic will also be down to one lane to allow crews to perform preventative maintenance on the passing lane to ensure the problem does not spread.

Motorists should slow down as they approach the work zone and plan for some delays.

ITD crews fixing potholes in East Idaho

EAST IDAHO – The Idaho Transportation Department is working to address potholes created by rapidly changing temperatures this winter. Recent snows followed by warm temperatures allows water to enter through cracks in asphalt. When that water freezes at night it can result in potholes forming on the surface of Idaho’s highways and freeways.

While winter maintenance typically focuses on keeping roads clear of snow, crews are also repairing potholes on I-15, within the city of Idaho Falls, as well as in other areas of the region.

D5 operations engineer Greydon Wright says, “The biggest area that we have been fighting them are on I-15 between Exit 93 (Blackfoot) and the Blackfoot Rest Areas.”

Similarly, D6 operations engineer Bryan Young reports they have been hard at work as well, “This week we have received numerous comments about the potholes in Idaho Falls. The Idaho Falls Maintenance Shed has successfully repaired the major potholes and will continue to repair the roadways as more potholes appear.” However, Young points out that repairs are weather dependent. So, drivers must still pay attention to avoid hitting a rough piece of pavement.

Patching during the winter consists of using a “cold patch” that is intended to be a temporary solution. Crews will return in the summer to perform more permanent repairs as needed. In addition, ITD has several projects scheduled this year to address older pavement throughout the region.

ITD Preparing Projects on I-86 Through Power County

AMERICAN FALLS – The Idaho Transportation Department is beginning the summer work schedule with several projects in the I-86 corridor through Power County. These projects include repairing the Rockland Exit 36 bridge, repairing the Sunbeam and Seagull Bay bridges, and a pavement preservation project along I-86 through Power County.

The Rockland Interchange repair is scheduled to begin in June and will consist of surface repairs, girder repairs, and the installation of a new waterproof membrane for the deck. Motorists should expect some delays.

The Sunbeam and Seagull Bay bridge repairs are scheduled to begin in early August. Both will undergo surface repairs and new concrete overlays. During construction, traffic will be moved to one side of the interstate via crossovers and slowed through the construction area. Motorists should expect some detours during this project.

The pavement preservation project will consist of a micro-seal application which is intended to extend the lifespan of the pavement. ITD currently plans to perform this work after the bridge repair projects are completed. The micro-seal application is scheduled to be completed by the end of September. During work there will be lane closures and reduced speeds in work zones.

Drivers are encouraged to check 511.idaho.gov or the 511 app for the latest updates on construction and road conditions.

Detour in place this week on Idaho Highway 46 in Twin Falls County

Work is expected to begin tomorrow (Tuesday, Dec. 1) on a culvert placement along Idaho Highway 46 north of Buhl from milepost 87 to 88. In addition to the culvert work, maintenance crews will also add material to the shoulder of the highway.

“This area currently has an open ditch with a steep slope,” ITD Foreman Phil Etchart said. “Adding a culvert will allow us to build out the shoulder which will help improve the safety of motorists by providing a buffer between the roadway and side vegetation.”

Adding material to shoulders also improves drainage and helps prevent moisture from seeping under the roadway and causing damage during freezing temperatures.

A detour will be in place for through traffic during working hours – 8 a.m. to 5 p.m. Northbound motorists will be diverted at the intersection of ID-46 and 4300 N. Southbound motorists will be diverted at the intersection of ID-46 and 4400 N.

Signs will be in place to direct drivers through the detour. Motorists are encouraged to slow down and watch for flaggers and equipment in the area.

Work is expected to be complete within the week.

Flooding in Central Mountains creates hazards, motorists urged to use caution

Flooding on ID-55 near New Meadows

Flooding from spring runoff is causing water to run or pool on top of U.S Highway 95 and Idaho Highway 55 throughout the Central Mountains. The Idaho Transportation Department is urging motorists approaching these hazards to use caution.

Heavy rain and melting snow is causing isolated hazards in the Weiser, Payette, and Salmon Drainages. This includes the cities of Weiser, Council, New Meadows, McCall and Cascade. Hazards created by flooding may be pooling, erosion, mudslides, rockfall, and water running over the top of roadways. ITD crews are out in force mitigating these hazards with warning signs and, where possible, cleaning up debris. The Department reminds motorists who come upon these hazards to exercise caution.

“In most areas, the water is only a couple inches deep,” said ITD Foreman in Council, Robin Freeman. “But hitting that water at 55 MPH can mess up your vehicle. I’ve had one car already hit a puddle at high speed. It killed the engine and the car is stuck in the middle of the road.”

ITD is asking motorists to drive well and stay engaged. Be on the look out for warning signs or flaggers and obey directions to safely navigate these hazards. For roadway conditions and hazard warnings, check 511 and know before you go.

Flooding sends debris crashing into bridges

Bridge Snag Removal

ITD crews in the Treasure Valley are on high alert around the clock as prolonged flooding sends debris down river, creating blockages on bridges.

Entire trees have been uprooted by Boise River flows that well exceed the average. Currently, the river is at 8800 cfs at the Glenwood St. measuring station. This brings the water level close to the bottom of the bridge. You can watch a video of crews clearing debris from the ID-52 bridge in Emmett below.

Increased debris and higher water levels create more hazards to bridges. Branches can catch on the supports or bridge girders, which can lead to a domino affect of accumulating debris. This debris can raise the river levels more and adds pressure to the bridge supports. Left unchecked, this could lead to catastrophic failure.

To combat this threat, ITD has crews monitoring the bridges. They routinely check for debris build up and signs of stress on the bridge. Several excavators are also parked by bridges, which can be used quickly to break up any build up.

By patrolling regularly and stationing equipment nearby for ready use, ITD is positioned to keep this year’s record flooding from causing disaster to our road system.
