ITD responds to 6.5 magnitude earthquake

two landslides fell across idaho highway 21

ITD maintenance and bridge personnel are cleaning up debris and inspecting infrastructure after a 6.5 magnitude earthquake shook the Idaho Central Mountains Tuesday night.

Several mountain highways saw rockfall on the roadway following the quake. That includes Idaho Highway 75 (ID-75) near Stanley, ID-21 north and south of Lowman, ID-55 between Horseshoe Bend and Cascade, and ID-52 east of Emmett. Maintenance crews were immediately deployed to clear these hazards from the roadway and ensure the road was safe for travel.

Aftershocks continue to rock the region, causing additional rockfall. Crews are patrolling these high-risk areas to actively clean rocks from the highway. ITD urges the traveling public to use caution when driving in these areas.

NO IMMEDIATE CONCERN FOR BRIDGES

After the earthquake, maintenance crews scanned bridge structures for damage. At this time, there has been no damage of concern noted and the highways remain open. As is always the case, if any issue is spotted, ITD will immediately close a bridge.

ITD’s Bridge Department is conducting more-detailed analysis of the situation. They are conducting additional analysis of structures closer to the earthquake’s epicenter. Over the next several weeks, inspections will be conducted on priority structures to determine whether damage has been done and repairs are needed.

IDAHO HIGHWAY 21 CLOSED BETWEEN LOWMAN AND STANLEY

A storm system dumped 27” of snow in the Canyon Creek section of Idaho Highway 21, from Grandjean to Banner Summit. This increased the risk of avalanches and ITD closed the highway at 2:00 p.m. Tuesday, several hours before the earthquake.

The earthquake did cause several slides to fall onto the highway in this section. Crews entered the area to begin clean-up Tuesday night and quickly found the landslides were extensive. The crew contacted U.S. Geological Survey, which informed them of aftershocks and the risk of additional landslides. The crew withdrew and will remain out of the canyon until USGS has determined the risk of aftershocks is reduced.

At this time, the number and extent of landslides on this section are unknown. There is no timeframe when crews can re-enter the Canyon and begin clearing the road. Additional repairs to the roadway may be required as well. The Department is advising it may be many days before this section of ID-21 re-opens. Idaho Highway 75 and U.S. 93 remain open to access Stanley.

ONGOING ESSENTIAL SERVICES

Per Governor Brad Little’s Stay-Home Order, the ongoing maintenance and operation of roads are essential services and will continue during the COVID-19 pandemic. ITD crews will continue to respond to rockfall and other hazards created by the record earthquake. Additional essential services, such as plowing snow, pothole repair, and striping will also continue. The Department is committed to safely executing its Mission: “Your Safety. Your Mobility. Your Economic Opportunity.”

ITD issues 90-day extension on expiring credentials, encourages use of online services

To reduce large gatherings of people, the Idaho Transportation Department’s Division of Motor Vehicle is instituting a 90-day extension on some credentials. The public is also encouraged to use the DMV’s online services rather than go to the county sheriffs’ and assessors’ offices for essential services.

The 90-day extension applies to driver’s licenses and non-commercial registration. If one of these credentials expires between March 1st and May 31st of 2020, you will have until June 30th 2020 to renew. Many of these can be renewed online.

“As each county office decides the best way to operate during the COVID-19 pandemic, ITD is committed to providing remote services online, by mail, or over the phone,” said ITD’s Division of Motor Vehicle Administrator Alberto Gonzalez. “Much of the business the public needs to do with the DMV can be done through one of those methods. This balances the need to preserve public safety with the need for essential government services to keep people and products moving.”

County offices are managed by both the county sheriff’s office and county assessor’s office. In total, there are 88 county DMV jurisdictions. Each jurisdiction has the authority to close its offices or change the way to conduct business.

Some county DMV offices have already closed and others are considering it. ITD encourages the public to call their county office before leaving to see the current status. Contact information for each office can be found at itd.idaho.gov/itddmv.

The following services are available online, through mail, or over the phone.

Driver’s license renewal (not for first-time Star Card)
Acquiring a replacement driver’s license or identification card
Paying driver’s license reinstatement fees
Purchasing a driving record
Vehicle registration renewal
Ordering personalized license plates
Checking status of vehicle plates and titles
Commercial vehicle oversize/overweight permits
Commercial vehicle registrations

Please note, the Oct. 1, 2020 deadline to use a Star Card (Idaho’s REAL ID) or other federally-approved identification for federal security at airports, military bases, or federal courts is outside the control of the State of Idaho. ITD and the Governor’s Office is in communication with our Congressional Delegation, the Department of Homeland Security, and the White House regarding this matter in light of the COVID-19 pandemic.

Overnight eastbound I-84 closure scheduled March 6 at Northside Boulevard (Exit 35)

The Idaho Transportation Department will implement a short-term overnight closure on eastbound I-84 at the Northside Interchange on Friday, March 6.

Beginning at 12 a.m. until 4 a.m., eastbound I-84 traffic will be detoured off the Interstate at Northside Boulevard (Exit 35). Traffic can use the interchange’s on-ramp to re-enter eastbound I-84. Travel will remain open on Northside Boulevard.

This closure will allow crews to safely perform roadway maintenance I-84. You can view a detour map below.

Work between ID-78 and the C-Line Canal will begin Monday, Feb.3

On Monday, Feb. 3, both lanes of traffic on Idaho 55 in Marsing between Highway 78 and the C-Line Canal will shift to the south. The traffic shift will accommodate curb, gutter and sidewalk work to be done on the north.

Both lanes of traffic will remain open. Flaggers will assist traffic.

Work is expected to take approximately three weeks to complete.

Northside Boulevard detours scheduled Friday and Saturday nights during interchange girder placement

NAMPA – Northside Boulevard will be closed overnight under I-84 Friday and Saturday (Jan. 31 and Feb 1) while crews place six steel girders for the I-84, Northside Interchange in Nampa.

Detour route for Northside Closure — *Detour route for Northside closure*

The girders will support the center half of the reconstructed interchange of I-84 and Northside Boulevard. Road closures will begin at 10 p.m. and will end at 7 a.m. each morning. One lane of I-84 will remain open in each direction. Flaggers will direct Northside Blvd. traffic through a detour route.

Southbound traffic on Northside Boulevard will be directed to enter westbound I-84, exit at the Karcher Road Interchange (Exit 33A), and travel eastbound on I-84 to access Northside Boulevard (Exit 35).
Northbound traffic on Northside Boulevard will be directed to enter eastbound I-84, exit at the Franklin Road Interchange (Exit 36) and travel westbound on I-84 to access Northside Boulevard (Exit 35).

“When completed in 2021, the new Northside Interchange bridge will be the longest single-span bridge in Idaho,” said Mark Campbell, ITD’s GARVEE project manager. “This is no small effort and we appreciate the patience of the traveling public.”

The girders will be delivered to the construction site in pieces and assembled in a closed lane of I-84. When assembled, each girder will be 5 feet, 10 inches tall and 220 feet long. The process will require close to 4,000 bolts and multiple large cranes.

ITD is replacing the Northside Interchange with a Single Point Urban Interchange for safer, more efficient travel. Work on the second half of the interchange bridge will begin later this year.

ITD & Governor’s Office collaborate to promote Traffic Incident Safety Week awareness

Idaho Gov. Brad Little and ITD collaborated Tuesday, Nov. 12 to bring attention to the importance of traffic incident responders during National Traffic Incident Management Awareness Week.

Gov. Little signed a proclamation Tuesday recognizing the importance of traffic managers and incident responders.

Roadway incidents can occur at any time and may require law enforcement, fire, emergency medical services, tow operators and transportation workers. The ability for them to respond quickly is critical for protecting life and reducing secondary crashes.

“The traveling public can do their part to protect responders by driving in an engaged manner and moving over when incident responders are present,” Gov. Little said.

Traffic incident responders in Idaho contribute substantially to caring for victims in these crashes, and the quick clearance of our roadways increases mobility of the traveling public and has the added benefit of greatly enhancing safety on the highways.

Ground depression prompts partial closure on Myrtle Street in downtown Boise

11:45 a.m. Oct. 8

During boring operations along Myrtle Street in downtown Boise, a depression formed in a travel lane, prompting a partial closure of the road.

Currently, the right-most lane of Myrtle Street is closed between 2nd and 4th Street. ITD crews are on site investigating the situation and developing a response. Motorists, bicyclists, and pedestrians are urged to use caution while traveling in the area.

Updates will be posted here as additional information comes in.

2:00 p.m. Oct. 8

Crews investigating the depression in the road have found the cause to be a void in the earth beneath the roadway. This void is estimated to be 3-4 feet deep, and 8-14 feet wide, or about the width of a single travel lane.

The boring work being done in the area is to relocate utilities. Idaho Power received a permit from ITD to complete the work.

The contractor (Idaho Power) will rip up the road surface to survey the extent of the void. Generally speaking, the next steps for the contractor will be to fill in the void with appropriate material and repave the roadway.

4:00 p.m. Oct. 8

Crews have opened up the road to survey the extent of the void. It ended up being less severe than anticipated. The void was no deeper than 18 inches and extended 14 feet wide. The contractor will spend the rest of the day filling in the void and laying a temporary asphalt patch to restore the surface of the road to a smooth driving surface. ITD has directed this work to be complete by 4:00 a.m. October 9th.

ITD will work with the contractor to complete extensive repairs and lay durable asphalt down at a later date.

9:00 a.m. Oct. 9 (final update)

The contractor worked overnight to repair the damage and patch the road with temporary asphalt. The lane was open before the morning rush hour. The contractor is working with ITD to plan a permanent repair at a later date with minimal impact to traffic.
