The bridge at the 2040 blk of Gypsy Bay Rd will be closed from Monday, Sept 28th to approximately Oct 10th for a rebuild. Please use Moonshadow Rd for the detour.
Paving will start on N Kootenai Rd from the intersection of Firestone Ln to Selle Rd on Monday Sept 28th. The project will take approximately one week. Please expect delays.
Helen Thompson Rd will be closed on Sept 16th @ Johnsons Creek from 7:30 am to noon
W Shingle Mill Rd will be closed on Sept 17th at approximately 100' south of Bobtail Rd from 8am to 4pm. Both for culvert replacements.
THIS BRIDGE REPLACEMENT PROJECT IN THE 5900 BLOCK OF RAPID LIGHTNING ROAD IS PLANNED TO BE COMPLETED IN THE NEXT 6 YEARS, BUT THE CONSTRUCTION DESIGN OPTION NEEDS TO BE SELECTED WITHIN THE NEXT MONTH. THE PROJECT IS PLANNED TO BE COMPLETED IN 2026 WHEN IDAHO DEPARTMENT OF TRANSPORTATION HAS IT SLOTTED FOR FUNDING, UNLESS FUNDING COMES AVAILABLE SOONER. THE WORK WILL BE CONTRACTED OUT AND THE CONSTRUCTION TIME FRAME IS MAY THROUGH OCTOBER IN YEAR OF CONSTRUCTION (TO BE DETERMINED). PUBLIC COMMENT MAY BE MADE TO THE ROAD AND BRIDGE OFFICE IN WRITING OR VIA EMAIL TO MATT.MULDER@BONNERCOUNTYID.GOV OR STEVE.KLATT@BONNERCOUNTYID.GOV.
SEE IMAGES BELOW FOR EACH OF THE 3 OPTIONS.
OPTION 1 - BONNER COUNTY ROAD DEPARTMENT *PREFERRED OPTION DUE TO COST - CLOSE ONE LANE TO BUILD HALF OF THE NEW BRIDGE THEN USE NEW SECTION WHILE THE REMAINING BRIDGE LANE IS BUILT. INCLUDES A TEMPORARY TRAFFIC SIGNAL AT EACH END OF CONSTRUCTION ZONE FOR 1 LANE TRAFFIC. WITH APPROXIMATELY A 3 MINUTE WAIT FOR ALTERNATE LANE OF TRAFFIC TO PROCEED THROUGH THE CONSTRUCTION ZONE.
OPTION 2 - NORTH ROUTE BUILD, KEEPING EXISTING BRIDGE AND ROAD OPEN DURING CONSTRUCTION OF NEW ROAD AND BRIDGE. - RESULTS IN 25% INCREASE IN COST OVER OPTION 1 DUE TO STREAM BED RELOCATION, BUILDING OF NEW ROAD BED AND INCREASED RIGHT OF WAY PURCHASE.

Reflections – Summer 2020
The past three months have been a most interesting time in the life of the Bonner County Road Department. Mid-March found us shuffling half crews on and off for the next six weeks, during which our summer construction schedule began to slip immediately. By the time we got our full crews working together again, Mother Nature decided to play pranks upon us with frequent and persistent rain events. Now, at the end of June, we are finishing our mag chloride treatments of early June.
The interruptions and rain delays have also upended our construction schedules for this year. We have been able to get a substantial amount of work done on North Kootenai Road, brushing work done up on Eastshore Road at Priest Lake, and several smaller roads graveled near Cocolalla Lake that have been waiting a few years. A project impacted by this year’s interruptions has been our BST project for Lakeshore Drive being split into road improvements later this year and surface treatment being completed next summer.
Chip sealing projects will get underway right after the Fourth in the Sagle area, move out to the Clark Fork area and then up to Priest Lake. Depending on what little tricks Mother Nature is hiding up her sleeves, we should be done with chips around the middle of August. We will have a crew working on brushing and ditches up Baldy Mountain Road, plus a contractor clearing right-of-way on Woodland Drive. We are working on setting up a guardrail project for an area on Denton Road and the striping of roads will get under contract before too much longer.
Bonner County got a unique opportunity to participate in planning efforts funded by the Federal Highway Administration to create a Local Roads Safety Plan. The numbers of serious and fatal crashes on local roads is disconcerting at best and I have wanted to study our crash data to determine if similarities in crashes exist that might be treated systemically for improved driver safety. This effort has been made a bit cumbersome by COVID 19 restrictions on travel this year, but getting traffic safety planners to help us analyze our road system is a good starting point. We have been awarded a grant for right-of-way clearing of hazard trees in a couple of years and that will help reduce the severity of future crashes.
We are working on a project to replace a small bridge that is failing out on the Gypsy Bay Road after summer traffic slows down and have a bridge deck restoration job scheduled up on Peninsula Road once we begin to have some warm days. There are three more intersection lights we will have installed on Highway 95 south of Sandpoint later this summer and will continue to expand our lighted intersection program each year. Hard to believe, but we are beginning to gather up our stockpiles of anti-skid material for winter already in a program that costs nearly $2 million each season. It has been good to add three new trucks to our aging fleet.
Let’s all drive safely and have patience with our crews working to improve your county roads.
Steve Klatt, Director

This project is progressing nicely. The culvert is installed and compaction of fill is underway. Weather permitting, Sunnyside Road should be reopened Friday by 4 pm.
Today, the contractor is working on Bayview Rd driveway transitions so property owners have quality access until the next phase of the road project is completed. Paving will begin Tuesday, September 18th and continue through September 23rd.
Bike path tunnel assembled and back fill is still underway. The project adds a designated turn lane and widens the intersection in addition to moving the bike path. It was slated to be completed October 1st, but is expected to be finished later this month. The contractor is making good progress rebuilding the roadway. Paving, painting lanes and installation of guard rails will need to be completed prior to reopening the intersection.

Building a temporary dam to divert stream during culvert replacement 10/13/2016
Construction of the culvert replacement on Cavanaugh Bay Rd at Soldier Creek has been delayed due to the weather and site conditions. The project was scheduled for October, which is typically a low water month with an average rainfall of 1.5”. Since construction began on October 10 th , we have had over 6” of rain, including one storm which qualified as a 3-yr storm event.
October 14th, unseasonably heavy rain floods temporary dam
Crews try to increase the temporary dam height efficiency
Because of the rain, the creek has risen from its typical 8” October depth to approximately 4ft deep. This has necessitated the installation of a second bypass pipe to handle the flows, as well as building the temporary coffer dam higher with ecoblocks and super sand bags. Even with these extra facilities, on two occasions the water has overtopped and undermined the coffer dam, sending water through the existing wooden structure once again. In one instance, it blew out a side of the cofferdam. It has become clear that the temporary ecoblock cofferdam is insufficient to block the flow of this quantity of water. Therefore, it was decided to install a sheet pile cofferdam which is taller and deeper and cannot be topped, undermined, or circumvented.

The soils in the excavation limits are a silty sand for the first 15ft, and then transition to a blue clay at approximately creek level. The saturation of the soils in the work site has turned everything into a deep mud pit, with men and equipment unable move, let alone work effectively. To continue work, it was decided to import 6” minus rock and place it on top of geotextile fabric and geogrid to create a ramp and pads on which equipment can safely and effectively operate. It was also decided to continue the sheet pile wall the entire length of the new culvert so that the final excavation can be made without the sides slumping in – an event which would pose an extreme safety risk to workers 10ft below the water level.
Heavy rains cause new strategy for diverting water – building a coffer dam wall with 30′ sheet piles

Please be advised of the upcoming road closure – Cavanaugh Bay Rd at Soldier Creek crossing for culvert replacement. Signs are posted at both ends of the closure. A primitive single lane 5 mile long detour road will be open during the road closure. Please note that this road will not be well suited to recreational vehicles and boat trailers, etc. Work is planned to be completed between October 3rd and November 17th.

Chip sealing projects are underway. Please drive with care and respect workers. We have a very limited (weather permitting) window to get these projects completed.

Images of the Old West draw people to an area once filled with miners, farmers, ranchers, loggers and other agricultural workers. Often newcomers are much more romantic about the West than the old timers and have false hopes about bringing their urban lifestyles into the great outdoors. They come with false expectations. They believe they can fax and email from the mountaintop. In the New West, the information superhighway is often a dirt road.
