Southwest Idaho highway construction report for July 4-11
BOISE - Following is an update on interstate and state highway construction projects in southwest Idaho.
ADA COUNTY
Interstate 84 East improvements - Soundwalls
Preparations are under way to build a soundwall on the north side of I-84 from Cole Road to Broadway Avenue. The wall will range from 14 to 16 feet high and will help reduce traffic noise for residents.
Over the next few weeks (anticipated completion July 11), crews will finish demolishing part of the existing soundwall (from the Flying Wye project five years ago) near the Cole Interchange. The wall, which tapers down currently, will be rebuilt to connect with the new soundwall. The demolition work will occur between 7 a.m. and 7 p.m. each day. No lane restrictions will be in effect initially, however, if necessary, the outside lane of westbound I-84 will be closed between the Orchard and Vista interchanges.
Support posts for the first new soundwall panel are expected to be installed next week (July 7-11).
The outside shoulder of westbound I-84 is closed to traffic at all times for the soundwall project, and the speed limit is 55 mph. Flaggers on the Vista and Orchard interchanges' westbound off-ramps may stop traffic briefly for construction vehicles entering and exiting the work zone.
Record Steel and Construction Inc. (RSCI) of Meridian is the contractor on this $9.5 million soundwall project.
The soundwall is one of several improvements planned for the I-84 East corridor in the next two years, including reconstructing the Orchard Street Interchange, reconstructing the Vista Avenue Interchange and widening I-84 between Cole Road and Broadway Avenue.
ADA & CANYON COUNTY
Interstate 84, Garrity to Meridian widening
Widening work is under way in the I-84 median between the Ten Mile Overpass and the Meridian Interchange. Crews are working day and night to excavate and fill the median to prepare for additional lanes on I-84.
The I-84 speed limit is reduced to 55 mph between the Garrity and Eagle interchanges. Inside shoulders are closed between the Garrity Interchange and the Meridian Interchange. Two lanes of traffic are open in each direction during the day (5 a.m. to 10 p.m.). At least one lane of traffic is typically open at night (10 p.m. to 5 a.m.)
The first phase of the project will widen the segment between the Ten Mile Overpass and the Meridian Interchange. The second phase will continue the expansion west to the Garrity Interchange in Nampa.
A third lane in each direction will be built in the median and a permanent barrier will be placed between east- and westbound lanes. The project also will reconstruct existing lanes between the Garrity and Meridian interchanges. Construction is expected to be complete in 2010.
Knife River Corp. of Bismark, N.D., is the contractor for the first segment of the $29.6 million project.
Thueson Construction Inc. of Nampa is the contractor for the $6.4 million median work between the Garrity Interchange and Ten Mile Overpass.
Temporary guardrail is scheduled to be placed at night along the inside shoulders of I-84 between Garrity and Ten Mile beginning Monday (July 7) and lasting about three weeks. Placing guardrail will require single-lane closures on I-84 at night. Work in the median will follow. The closures will extend to Franklin Boulevard for survey work.
The project is part of a series of improvements planned for I-84 between Caldwell and Meridian. Construction of a new interchange at Ten Mile Road is anticipated to begin in Summer 2009 and be complete in Summer 2011. A separate project will rebuild the overpasses at Robinson and Black Cat roads to accommodate four lanes in each direction on I-84. Overpass reconstruction is expected to begin this fall and be complete next year.
The above projects are part of the GARVEE Transportation Program, which uses funds from Grant Anticipation Revenue Vehicle (GARVEE) bonds to expedite interstate improvements.
CANYON COUNTY
CALDWELL - Interstate 84, Exit 29/Franklin Interchange rebuilding
The rebuilt Exit 29/Franklin Road Interchange wll be dedicated in a ceremony Tuesday (July 8) at 11 a.m. The project improves access to Caldwell from I-84, improves traffic flow and eases congestion. The old two-lane Franklin Overpass was replaced with a six-lane bridge. The new overpass has two through-lanes in each direction and dual left-turn lanes in each direction.
The interchange rebuilding, which started in early December 2006, enhances several aspects of the interchange. Ramps were lengthened and widened to two lanes at their intersection with Franklin.
The project also involved widening Franklin Road from two to five lanes between the overpass and Specht Avenue. The new road has a curb, gutter, sidewalk and bicycle lanes.
Concrete Placing Company of Boise is the contractor for the $24.8 million project.
CALDWELL - Chicago Street and 21st Avenue
Traffic is reduced to one lane in each direction through the end of July for the completion of improvements at the intersection of Chicago Street and 21st Avenue in Caldwell.
The project will widen both Chicago Street and 21st Avenue at the intersection to add a left-hand turn bay on 21st Avenue, and add traffic signals, construct sidewalks, curb and gutter, and enhance the stormwater drainage facilities. It is the first of several enhancements to 21st Avenue between Chicago Street and Franklin Road.
WF Construction and Sales LLC of Meridian is the contractor on this $448,145 project.
PARMA - U.S. 95, Parma Business District and 4th St. to Roswell Blvd. sidewalk
These companioned State and Enhancement projects will mill and inlay the pavement through Parma, address ADA (Americans with Disabilities Act) access issues and install lighting from 4th Street to Roswell Boulevard in town. Crews also will replace curb and gutter and install 7.5-feet-wide sidewalks on both sides of the road from Roswell Street to Fourth Street. Decorative lighting (eight poles) also will be added in that area.
There will be minor delays between Roswell and 4th. The delays will be no more than 15 minutes. The contractor will use flaggers to direct traffic through the area, but two-way traffic will be maintained.
The road will remain open at all times. There are currently three lanes through town, including a center turn lane, so traffic can be shifted as required and the road will remain open.
The project started May 12 and should be completed in late July.
The curb, gutter, sidewalks and lighting are being done with the town's enhancement funds. The mill and inlay of paving are being done with state funds.
Knife River Corp. of Bismark, N.D., is the contractor on this $747,000 project.
ELMORE COUNTY
MOUNTAIN HOME - American Legion Boulevard overlay
This project will rehabilitate about three-quarters of a mile of American Legion Boulevard (I-84B) through Mountain Home. The pavement rehabilitation will extend the life of the roadway in this section.
The road was built in 1960, with only periodic improvements since.
The project also will upgrade substandard pedestrian ramps at nine intersections, in accordance with ADA (American with Disabilities) guidelines.
Traffic will be reduced to one lane between North 2nd East Street and North 14th East Street. Motorists will be assisted through the work zone by flaggers at North 2nd East, South 3rd East, North 10th East and North 14th East.
Knife River Corp. of Bismark, N.D., is the contractor on this $546,405 project.
The project is scheduled for completion in late July.
NEAR MOUNTAIN HOME - Simco Road to Mountain Home resurfacing
Roadway resurfacing work to level a section of I-84 near Mountain Home is scheduled to get under way on Monday (July 7).
Both the eastbound and westbound travel lanes of eight miles of the interstate, from Simco Road (milepost 82) to the first Mountain Home exit (milepost 90), will be milled and paved. All lanes will then be treated with an edge-line to edge-line seal coat that will protect the surface and improve traction for motorists.
During the work, the speed limit in the work zone will be reduced to 45 mph, and motorists will be limited to one lane. Of the total eight-mile stretch of roadway, the contractor will be working on two miles at a time, and the reductions will only be in effect in that rolling two-mile section.
Central Paving Co., Boise, is the contrqactor on this $1.9 million project.
The project is scheduled for completion in mid-August.
SOUTH OWYHEE COUNTY
Duck Valley Indian Reservation to Sheep Creek Road
This pavement rehabilitation project will overlay Idaho 51 to extend the life of the roadway.
During the work, 8.5 miles of the highway will be repaved, from the Duck Valley Indian Reservation to Sheep Creek Road just north of the reservation.
The pavement rehabilitation will use the CRABS (Cement Recycled Asphalt Base Stabilization) process. CRABS involves grinding the existing roadway down to the gravel base, then adding cement to the old asphalt.
Traffic will be reduced to one lane on this two-lane road, with flaggers and a pilot car guiding motorists through the work zone. The speed limit also will be reduced to 55 mph.
Debco Construction of Twin Falls is the contractor on this $2.1 million project.
The project is expected to finish in mid-July.

WASHINGTON COUNTY
WEISER - Snake River Bridge replacement
The Snake River Bridge on the U.S. 95 Spur in Weiser will be replaced and widened. The bridge connects Annex, Ore., to Weiser.
A bridge was built in 1903, with an additional span added in 1911. Traffic signals were added in 1949. In the 1950s, the bridge was replaced, and that is the one being rebuilt today. Once completed, the bridge will be 16 feet wider and able to carry heavier traffic volumes. In addition, the road on both sides of the bridge will be reconstructed.
New curb, gutter and sidewalks will be reconstructed on the Idaho side of the bridge.
Lane closures are in effect on the west ramp on the Idaho side of the bridge. Motorists will use the east ramp in both directions to access and exit Old Highway 70 at the bridge.
The speed limited is reduced to 25 mph on the Oregon side of the bridge.
Sletten Construction of Boise is the contractor on this $10 million project. The project is expected to be completed in 2010.
