The sign locations are on Idaho 21 at the junction to Warm Springs, Idaho City, Lowman, and Stanley. And on the Banks to Lowman Highway at Banks, and Idaho 55 near the Shadow Valley Golf Course.
Old signs and cabinets have been removed and new concrete sign bases and cabinet bases installed at Banks and on Idaho 21 at Warm Springs, Idaho City, Lowman and Stanley.

Idaho 21 resurfacing to Lowman
A resurfacing project covering 20.4 miles of Idaho 21 in Boise County is wrapping up for this construction season. Crews will return in the spring, and finish in Oct. 2013.
The project runs from Mores Creek Summit to Clear Creek Bridge below Lowman, adding a Stress-Absorbing Fiberglass Layer with Emulsified Asphalt (SAFLEA) on two adjoining sections of Idaho 21 (milepost 52.3 to 60 and 60 to 72.7), conducting slope stabilization, and upgrading guardrail at existing locations.
A SAFLEA treatment is a seal coat with a coating of chopped glass fibers between the oil and gravel aggregates to enhance durability and reduce cracking.
Crews are finishing guardrail installations this week.
Knife River Corp, of Boise, is the contractor on this $3.9 million project.
CANYON, OWYHEE COUNTY
Idaho 55 resurfacing in Marsing, Caldwell
A resurfacing project is wrapping up at two locations between the Snake River Bridge in Marsing and Pride Lane in Huston, which is just to the west of Caldwell. The project extends 8.5 miles north from the bridge.
Work on this short project, which involves recycled asphalt and an overlay treatment, is expected to finish by the end of November. The two project locations are separated by just a few miles.
One lane of traffic will remain open, and motorists will be guided by flaggers on this two-lane road. The speed limit will be reduced to 35 mph in the work zone, and brief delays are expected. The delays should be 5-15 minutes typically, and up to 30 minutes if crews are working on the lower and upper sections at the same time and drivers get caught at both stops.
Crews paved the top lift Monday (Nov. 19) and are re-seeding. Paving will be completed by the end of the month, pending good weather.
Knife River Corp. Northwest, of Boise, is the contractor on this $933,000 project.
CANYON, PAYETTE COUNTIES
I-84 median leveling, Black Canyon to Sand Hollow
The median of Interstate 84 near Sand Hollow, a few miles east of Black Canyon, is being leveled in a project expected to finish by the end of the month.
Crews are removing the berms in the median of the interstate. The leveling is a safety improvement to minimize water runoff that created soft-spot hazards in the median.
The speed limit is reduced to 65 mph weekdays (during the day) between milepost 13 (Black Canyon) and 17 (Sand Hollow), and the inside (left) lanes will be coned off in each direction during the work.
Crews have nearly completed activities. They still need to install catch basins and re-seed the project area.
Irvco Asphalt & Gravel Inc., of Fruitland, is the contractor on this $235,000 work.
CASCADE – Bridge Replacement
A replacement of the North Fork Payette River Bridge in downtown Cascade is now under way. The bridge work will extend into summer 2013.
This project will replace the old, narrow, width-restricted bridge built in 1933 with one more than twice as wide. The existing bridge is 24 feet wide, and will be replaced with a 60-foot wide, 393-foot long, three-span bridge. The new bridge will have two 12-foot lanes, two 11-foot shoulders and a 14-foot median.
In addition, a paved extension will be built to the dirt shared-use path under the bridge on the north side of the river that provides access from both sides of the bridge to the new riverside park.
In the first stage, two-thirds of the new bridge will be built to the west of the existing structure. Traffic will be maintained on the existing bridge through this first stage of bridge work, and then will be routed to the new section of bridge for the remaining work as the old bridge is demolished. There will be traffic interruptions while the new roadway section leading to the new bridge is built.
This week, the contractor set four span 1 girders. Next week, they plan on setting span 2 and 3 girders on Tuesday and Thursday (Nov. 27 and Nov. 29). Motorists can expect up to 15-minute delays.
Work shut down Wednesday afternoon (Nov. 21) and crews will not return until Monday (Nov. 26).
From Monday through Thursday, work that limits drivers to one lane in each direction is only allowed between 9 a.m. and 4 p.m. Two lanes will be maintained between noon Friday and noon Monday. A river safety and navigation plan will be in place for recreationists that use this section of the river.??
