The public is invited to an open house next Tuesday, June 18 to learn about safety improvements planned for US-95 near McArthur Lake south of Naples.

The meeting will last from 4 p.m. to 7 p.m. at Naples Elementary (145 Schoolhouse Road), with members of the public welcome to attend at any time to ask questions and give comment.

Planned to start construction in 2022, improvements include reconstructing one mile of the highway to realign sharp curves and replace the culvert at Deep Creek.

The culvert will be replaced with a 300-foot bridge with enough clearance for wildlife to pass underneath rather than cross the highway.

More information is available at itdprojects.org/us95mcarthurlake, and comments will be accepted online until July 2.

As part of ongoing construction to repair bridges on Interstate 90 and overpasses in Post Falls, crews will close two ramps at Spokane Street this weekend and next week to apply a sealing treatment to protect the driving surface.

The westbound on-ramp will be closed the weekend of Friday, June 7 but will be open for the morning commute on Monday, June 10. Following that closure, the eastbound off-ramp will be closed Monday night (June 10) through Friday night (June 14). Nighttime closures are planned from approximately 7:30 p.m. to 5:30 a.m.

Conditions on I-90 near the Huetter and Atlas bridges are expected to revert back to normal by the end of this week but work will continue on overpasses at night until early July.

Another project to reduce rutting from the Washington-Idaho border to the Northwest Boulevard exit in CDA will begin in July and last until September.

Maintenance on Veterans Memorial Bridge over Bennett Bay is scheduled to begin today, June 3, with work requiring lanes to be reduced for the next month.

The driving surface of the bridge will be sealed to repair and protect the bridge deck. Over the next several weeks, the interstate will be reduced to one lane in each direction.

This bridge is one of several structures on or over Interstate 90 undergoing maintenance. To learn more about the project, visit itdprojects.org/i90bridgessv.

Update as of June 3, 2019 at 1:30 p.m.:

A temporary signal will be in place by the end of the week at US-95 and Kathleen Avenue in Coeur d’Alene.

While the signal is being installed, drivers can expect intermittent lane closures on the highway and Kathleen Avenue. Once in place, the temporary signal will allow all normal movements.

At this time a permanent structure will be included with other scheduled highway improvements.

 

Original post:

The signal at US-95 and Kathleen Avenue was removed after a driver ran into it Sunday morning and will likely not be replaced for a few months. 

Traffic on the highway is currently free flowing with stop signs on Kathleen Avenue. Right turns off and onto the highway are the only turns allowed.

Drivers are not able to make left turns or cross the highway at the intersection. Instead, drivers are advised to use Government Way and Ramsey Road to access the nearest signals on US-95 at Dalton and Neider avenues. View a map of the area.

Traffic will likely remain in this configuration for a few months. ITD is investigating the structural integrity of the signal’s bases and exploring intermediate options to replace the structure. Signal replacements of this kind typically take time to fix as these structures are often custom-built and expensive to keep on hand. 

A permanent fix will likely be incorporated into construction already planned for the next two summers on US-95 in CDA. Learn more about that work by visiting itdprojects.org/us95intersections.

Work began Monday, May 20 to repair two slides that fell in April 2017 on ID-57 just north of Priest River. Repairs are expected to take about one month, during which the highway will be reduced to one lane with a temporary signal present to guide alternating traffic. 

On the west side of the highway, crews will excavate material and construct a rock inlay to help stabilize the slope. On the east side, gabion baskets, or cages full of rocks, will be installed. The highway will also be reconstructed. 

 Earthworks Northwest is constructing improvements for approximately $540,000.

Idaho Highway 97 is scheduled to be closed this week to allow construction of a pedestrian tunnel for Camp Easton north of Harrison. The closure is expected to begin Tuesday, May 7 and last no later than May 16.

Drivers are advised to use Burma Road as a detour while the 10-foot wide tunnel is being constructed at the current location of the camp’s crosswalk.

The tunnel and associated project features are funded by a $230,000 grant from the federal Transportation Alternative Program (TAP). East Side Highway District sponsored the application. The Boy Scouts of America Inland Northwest Council contributed an additional $45,000 as a match.

Per the grant application, an average of 220 campers must cross the highway multiple times each day during the summer to access both sides of the 383-acre camp.

TAP grants can be used for a range of projects from on- and off-road pedestrian and bicycle facilities to safe routes to school education projects. This program is authorized to fund $850 million in improvements across the nation this year.

Repairs to the Atlas and Huetter bridges on Interstate 90 are halfway complete, and by this weekend crews will start working on the remaining halves of the structures, requiring a change in the construction zone.

Once the next phase of work starts, westbound lanes will be divided before the bridge over Atlas Road, with one lane remaining in place for access to the rest area near Huetter and the other lane crossing the median to join eastbound traffic over the bridges. All drivers heading to the rest area will need to take the right lane. Both lanes will have access to the Idaho Highway 41 exit.

View a graphic showing traffic impacts.

Other work in the construction zone this week will apply striping and smooth the surface on I-90 from Northwest Boulevard to Ninth Street, requiring a single-lane closure at night. Crews will work on the eastbound lanes before finishing westbound lanes, with work anticipated to last four nights and planned to start tomorrow (May 1).

Bridge repairs expected to be completed by early July and will be followed by another project to reduce rutting from the Washington-Idaho border to the Northwest Boulevard exit. Resurfacing will last until September.

Boat check stations across the state are now open, including the one on Interstate 90 near Cedars, where inspectors found the greatest number of contaminated watercraft in 2018.

Primarily positioned near state borders, stations check for aquatic invasive species (AIS), such as zebra mussels, being transported between watersheds. Key to this effort is signage provided by the Idaho Transportation Department to advertise inspection opportunities and patrols by local law enforcement to ensure motorists remember to stop.

The stations are part of a larger effort by the Idaho State Department of Agriculture (ISDA) to prevent the spread of AIS.

“The spread of aquatic invasive species like the mussels would threaten the Idaho we know and love,” said Nic Zurfluh, a section manager for ISDA.

Invasive mussels are easily transported, and once attached to an area, can quickly take over and are hard to eradicate. Colonies clog pipes in water systems, threatening hydropower and irrigation for food, as well as municipal water supplies. When they take over a lake, it can quickly lose its recreational value.

“If quagga or zebra mussels were to infest Idaho’s waters, as they have done in other states, it could cost the state nearly $100 million annually in damage and lost revenue,” Zurfluh said.

Invasive mussels are thought to have been carried over by transoceanic shipping containers through ballast water in the late 1980s. They started in the Great Lakes, and since then, they have been transported down the Mississippi Basin and to the west.

Shortly after the invasive mussels were found in Arizona’s Lake Mead in 2007, Idaho began monitoring lakes and rivers.

“Now we’re seeing more overland transportation,” Zurfluh said.

The Columbia Basin is the remaining major watershed in the United States that has not been infested, inspiring a regional effort between Montana, Oregon, Washington, Idaho and even Canada to share data, outreach strategies and prevention efforts.

Fifty fouled watercraft—ranging from boats to kayaks to barges—were found across the state last year through 110,000 inspections, though none were carrying viable organisms. To date this year, 10 fouled boats have been found.

“The opportunity for prevention is alive and well,” Zurfluh said.

To protect Idaho’s waters, watercraft users can remember three simple rules: clean, dry and drain.

• CLEAN watercraft and equipment before leaving any waterbody.
• DRAIN water from all equipment.
• DRY all vessel compartments and lay equipment out to dry before using in a different body waterbody or watershed.

For those recreating in the Coeur d’Alene area, note that the Coeur d’Alene River and the St. Joe River are part of different watersheds, requiring extra care between trips. More information is available at: http://invasivespecies.idaho.gov/watercraft-inspection-stations.

Beginning next week, a project to repair 17 structures on US-95 from Plummer to Westmond will begin.

Repairs will include overlays and some demolition, although work and impacts will vary from bridge to bridge. Drivers can expect at least one lane open.

Prominent bridges include several structures near the ID-58 interchange, Bunco Road overpass and the Athol interchange. All work is expected to be completed after September.

Contractors are typically expected to be on site during weekdays. They will likely spend a few weeks at each bridge before moving on to the next, with some overlapping work possible.

Repairs to Bunco Road overpass near Silverwood will be done at night to minimize impacts to traffic. Those repairs are currently scheduled for July.

More information can be found online at itdprojects.org/us95bridges.

Beginning in late April, contractors will start removing hazard trees along two miles of Interstate 90 near Fourth of July Pass to enhance highway safety. Trees can be hazardous when they fall, shade roadways and cause icy conditions in winter as well as hide any approaching wildlife.

Work will last for approximately one month during which travelers can expect work on the shoulders. Trees on the eastbound side will be removed first, followed by trees on the westbound side. Impacts are expected to be limited to the two lanes closest to the work.

Drivers may encounter single-lane or possibly two-lane closures of I-90. Full closures will be less than 10 minutes and may be necessary when logging tall or dead trees near the interstate. Crews will determine the need for and timing of these closures on site.

The contractor will remove dead and dying trees from 200 acres of state property while also harvesting other trees in the area to cover operating costs.

“It’s important to do this work when we can because trees can fall on the road or act as obstacles when people drive off the road,” operations engineer Jerry Wilson said. “We’ve found a way to let experts remove these trees at no extra cost to the taxpayers, while enhancing their safety.”

In the past, ITD has hired help to remove trees that could not be safely removed with its own employees and equipment, with a recent contract charging $1,000 per tree.

“Given the number of trees that need to be removed in this section, that wasn’t feasible,” Wilson said. “If this process works well, ITD could continue to use similar partnerships to increase safety along the entire corridor.”
