Talk about Culture Shock!

Idaho Transportation Department North-Central (District 2) Materials Engineer Chad Clawson, who has been with the department for 18 years, was informed Feb. 16 that he earned a 2018 Transportation Management Fellowship from the American Association of State Highway and Transportation Officials (AASHTO).

He will leave tiny Genesee (pop. 958) and report to Washington, D.C. in April for the year-long commitment. There are about 680,000 people in the D.C. area proper, with a metro-area population of more than five million people.

“My initial reaction was disbelief, then excitement and internal panic; really, it was difficult to contain my excitement,” said Clawson. “This is going to be a great opportunity for personal and professional growth.”

In his nomination letter in November 2017, Chad was most intrigued by the exposure to transportation and infrastructure planning on a larger scale than is typically afforded him in Idaho.

He is excited to bring that big-picture thinking to his position within ITD, benefiting road users. “I look forward to synthesizing ideas — then bringing them back to our department, and showing Idaho pride to the rest of the nation.”

Clawson said the year with AASHTO will be spent working on a broad range of technical issues with design, traffic engineering, materials and operations. “There will be reauthorization of the Fixing America’s Surface Transportation (FAST) Act, committee policy work, and a good deal of traveling. I will have direct involvement with topics at a different level that directly affect our safety, standards, and business practices here at ITD.”

Clawson works in planning and project delivery for ITD District 2, helping prioritize a construction budget of about $15 million annually.

LEWISTON—During the upcoming construction season, US-12 in north-central Idaho will undergo a $17 million transformation to revitalize aging infrastructure and improve safety throughout the corridor.

More than 50 miles of the highway between Lowell and the Idaho-Montana border will be repaved, and two bridges—over Maggie and Fish creeks—will be replaced.

“We are excited to have this opportunity to improve the corridor,” said Joe Schacher, the ITD manager for the improvements. “Some sections of the highway have deteriorated significantly due to heavy use and harsh weather conditions, and the bridges haven’t received major repairs since they were built in the early 1950s.”

Knife River Corporation will resurface 27 miles between Tumble Creek and Saddle Camp Road and another 23 miles between Warm Springs Pack Bridge and the Montana border. Repaving the highway will cost $13.3 million, Schacher said.

Concrete Placing Company will replace Fish Creek Bridge, and Braun-Jensen Inc. will replace Maggie Creek Bridge for a combined cost of $3.6 million, Schacher said.

Schacher said construction throughout the corridor could begin as early as April and conclude as late as October. Work will be suspended during travel-heavy holidays such as Memorial Day, the Fourth of July and Labor Day to minimize impacts to the traveling public. ITD has also coordinated with the USDA Forest Service to reduce effects to participants in Lochsa Madness and other events.

“US-12 is a critical access route for visitors planning a trip to the forest and the many recreation sites the Forest Service has in the Lochsa corridor,” says Jennifer Becar, public affairs specialist for the Nez Perce-Clearwater National Forests. “We appreciate the work ITD will be doing to improve access along this route and will be working closely with them to make sure our visitors are aware of upcoming travel impacts.”

Drivers can expect significant delays while traveling through the corridor. Given the number of projects in the area and the limited passing opportunities on the predominately two-lane highway, Schacher said travelers could experience delays upwards of two hours.

“Although it may not be ideal to oversee four different projects in one season, we were able to take advantage of the available funding,” said Doral Hoff, the engineering manager for ITD’s District 2. “The public can be assured that after this construction-intense summer, they won’t see ITD working on the highway for a while.”

A few years after these improvements, contractors will add seal coats to approximately 60 miles of the highway to protect the new road surface and extend the life of the fresh pavement, but other than that, Hoff said he does not anticipate construction for another two to three years.

As construction nears, the public can find information about specific construction dates through the project website at itd.idaho.gov/us12 and by visiting 511.idaho.gov. Travelers can also find construction information through the Montana Department of Transportation’s traveler information webpage at www.mdt511.com.

LEWISTON – Crews are stabilizing the slope by Idaho Highway 3 near Kendrick to prevent future landslides like the one that cracked the roadway last spring. That work is underway and is expected to continue through January 2018.

Knife River Corporation, the contractor for this $3.3-million project, began construction of a soil nail wall on the Bear Ridge Grade in late October. The soil nail wall will secure the area by installing a grid of steel bars, reinforced by a concrete retaining wall, that extends beyond the affected area of the slide into stable material in the hillside.

There are no impacts to traffic at this time near the construction site at milepost 15.7 but drivers are advised to reduce their speed to 35 mph as work is being performed on both sides of the highway.

In conjunction with the soil nail wall, the contractor will also replace a broken culvert underneath the road. The road will be reduced to one lane at that time.

“The soil nail wall, in addition to the new culvert, will greatly reduce the likelihood of another landslide by securing the slope,” said Riley Bender, Idaho Transportation Department project manager for the repairs.

ID-3 repairs are expected to be finished by the end of next August, including repaving 6.4 miles of the highway from the top of Bear Ridge Grade to Texas Ridge Road.

What was once a wind-blown wheat field near the small Idaho town of Genesee is now an environmental success story. A dozen years later, ITD has created a thriving, marshy wetlands area where one never existed before.

Genesee, a town of fewer than 1,000 folks, is a quiet community resting in the rolling hills and prairie that dominate Idaho’s Palouse country, midway between Moscow and Lewiston. When road construction on U.S. 95 in the spring of 2005 from the top of Lewiston Hill to Genesee required using some land designated as wetlands, ITD spearheaded a mitigation project to construct wetlands as compensation.

The project became known as “Cow Creek Wetland,” located along a half-mile of Cow Creek in Latah County next to Genesee between two county roads — Morscheck and Kreier

ITD eventually created almost 11.5 acres of wetland and riparian area to mitigate for area impacted by the highway project, at a cost of $1.5 million.

Construction started in 2005, as there were wells drilled at each corner of the area to provide water for the irrigation system and help plants get established. Excavation, irrigation system and initial plantings were completed that year. Nearly 24,000 containerized trees and shrubs were part of the mitigation plan. In addition, there were almost 35,000 plugs of wetland grasses, rushes, sedges, and more planted in 2005.

Then came the winter of 2005/2006, when roughly 90 percent of those wetland plugs were lost due to frost heaves. So, planners returned to the drawing board.

Spring of 2006, wetland areas were broadcast-seeded to compensate for the loss that first winter. In addition to seeding and planting, trees removed during the project were placed in the wetland as habitat snags, and in November of 2007 an additional 2,500 containerized plants were planted as warranty to replace trees and shrubs that had died.

The irrigation system, installed to provide watering as the vegetation got established, was turned off in 2008 to encourage plants to acclimate to their natural conditions.

By August of 2010, the U.S. Army Corps of Engineers stamped the site as completed.Many Genesee residents, who also use it for bird watching, today use the Cow Creek Wetland as a walking trail.

Most impressively, it is used as a wetland ecology classroom by the local high school.
