Southwest Idaho highway construction report for Jan. 28-Feb. 4

BOISE - The following projects are part of the GARVEE Transportation Program in southwest Idaho, which uses funds from Grant Anticipation Revenue Vehicle (GARVEE) bonds to expedite highway projects.

 

BOISE - Interstate 84, Cole Road to Broadway Avenue widening

ITD is rebuilding and widening east- and westbound I-84 between the Cole and Broadway interchanges in Boise. When complete, the interstate will have four lanes in each direction.

 

Overnight I-84 ramp detours will affect westbound motorists between Broadway and Orchard the nights of Feb. 1, 2 and 3 while overhead signs are installed. One lane of westbound I-84 will be open at all times, but various westbound ramps will be closed for motorists getting on or off the interstate.

 

Detours will be in place between 10 p.m. and 5 a.m. each night.

-       On Tuesday night (Feb. 1), motorists will not be able to exit westbound I-84 at Vista Avenue (the Boise Airport).

-       On Wednesday night (Feb. 2), westbound motorists will not be able to exit westbound I-84 at Vista Avenue or enter westbound I-84 at Broadway.

-       On Thursday night (Feb. 3), westbound motorists will not be able to enter westbound I-84 at Orchard.

 

Traffic will be directed each night through a detour route south of I-84. The detour route will go to the airport as well as roads where motorists can re-enter I-84. Maps are posted at www.itd.idaho.gov.   

 

Concrete Placing Co. Inc., of Boise, is the contractor. This $35.9 million project is expected to be complete in summer 2011.

 

MERIDIAN - Interstate 84, Ten Mile Interchange construction

Work continues on a project to construct a new interchange with on- and off-ramps at Ten Mile Road.

 

All lanes on Ten Mile Road are closed between Franklin and Overland roads. The Meridian Police and Ada County Sheriffs Department are enforcing the area. Violators will be ticketed for reckless driving.

 

Crews will be finishing manholes and hauling dirt on Tasa Drive between Overland and the Tasa Bridge during the week of Feb. 7.

 

The speed limit is 55 mph on I-84.

 

Idaho Sand & Gravel, of Nampa, is the contractor on this $33.8 million project, which is expected to be complete in summer 2011.

 

The landscaping, under a separate $580,000 contract to Franz Witte Landscape Contracting, is set to begin this spring when the ground thaws.

 

NAMPA - Franklin to 11th interstate widening

On the project to widen Interstate 84 between the Franklin Boulevard and Garrity Boulevard interchanges in Nampa, work is progressing on concrete paving in the median. These newly paved sections will eventually carry traffic.

 

Crews are working on several concrete-related tasks, including parapet work on the Union Pacific Railroad (UPRR) bridge and concrete foundations for overhead sign structures. Construction of two new bridges over the UPRR and Phyllis Canal is nearly complete. Replacement of the bridges will accommodate additional lanes on I-84.

  

No traffic impacts are expected for any of these construction activities.

 

This project is expected to be complete by early summer 2012.

 

Concrete Placing Co. Inc., of Boise, is the contractor on this $22.2 million project. 

 

Once these interstate improvements are complete, I-84 between Franklin and Garrity will be widened to three lanes in each direction, with an additional auxiliary lane for eastbound traffic. The auxiliary lane will allow motorists to enter I-84 at Franklin, remain in the lane farthest right, and exit at Garrity - never having to merge with interstate traffic.

 

NAMPA - Interstate 84, Garrity Interchange Bridge reconstruction

Construction on the I-84 Garrity Interchange improvement project continues. The project replaces two bridges on I-84 at the Garrity Interchange with a single bridge to accommodate three lanes in each direction on the interstate. Traffic impacts are the same as last week.

 

Work also includes reconstructing the interstate about a mile east of the interchange to tie into the widening of I-84 between the Garrity and Meridian interchanges, and removing the bridge piers in the roadway at Garrity Boulevard.

 

Once the piles are in place and finished, girders will be set allowing for the bridge deck to be formed. Crews are looking to set girders around Feb. 12, if weather permits and work goes as scheduled. The bridge girder work will be performed at night (10 p.m. 5 a.m.) and will require a closure of Garrity Boulevard.

 

This project is part of ITD's plans to improve I-84 between the Franklin and Garrity interchanges in Nampa.

 

The completed improvements will include three lanes in each direction from the Franklin to Garrity interchanges, and eventually four lanes in each direction from the Garrity to Meridian interchanges.

 

The entire project is being constructed in three stages:

 

COMPLETED

Step 1 - Build the median section of the bridge between the existing bridges. Traffic will remain on existing bridges, with two lanes open in each direction.

Step 2 - Remove the existing westbound bridge and build a new westbound portion of bridge. Westbound traffic will be moved onto the new median section. Two lanes will remain open in each direction.

CURRENTLY UNDER WAY

Step 3 - Remove the existing eastbound bridge and build a new eastbound portion of bridge. Westbound traffic will be shifted onto the new westbound portion of the bridge, and eastbound traffic onto the median section.

Completion - By summer 2011, three lanes will be open in each direction over the bridge, eventually connecting with a fourth lane in each direction east of the interchange.

 

Concrete Placing Co. Inc., of Boise, is the contractor on the $15 million project.

 

Following is an update on non-GARVEE state highway construction projects in southwest Idaho.

 

ADA COUNTY

BOISE - Floating Feather Road/Idaho 16 intersection turnbay project

A project to add a turnbay to the intersection of Floating Feather Road to serve north- and southbound traffic is expected to begin soon. Traffic control was set Thursday (Jan. 20) and the project is expected to begin Monday (Jan. 24). Initial work will include mobilizing equipment and saw cutting the culvert ends. 

The bridge must be completed by March 15, in time for the irrigation season. The roadwork will finish by May 1.

A 10-foot irrigation structure (concrete box culvert) exists within the project's limits and will be extended on both sides of Idaho 16 to allow for the lane addition. The project also involves some road widening.

During the project, traffic will use one lane in each direction, just as it is now. The speed limit will be reduced to 45 mph.

 

The contractor has posted Shoulder Closed Ahead traffic-control signs for both southbound and northbound traffic.  The speed limit has been reduced to 45 mph in both directions. Crews are saw cutting the ends off of the culvert.  Over the next few weeks, crews will place base material and work towards constructing the extension ends.  The work will take place just off the roadway.

 

The contractor hauled in roadway base material Thursday and Friday (Jan. 27-28).

Deer Flat Sand & Gravel Inc., of Nampa, is the contractor on this $266,000 project.

BOISE COUNTY

East of Boise - Mores Creek Bridge upgrade

A project to update the Mores Creek Bridge (commonly known as the High Bridge) on Idaho 21 east of Boise is under way.

 

During this work, the bridge deck and joints will be rehabilitated and the bridge parapet and railing replaced. Work on the foundation during the low-water winter period will include a retaining wall, rock anchoring, slope armoring, and seismic retrofit.  Portions of the structural steel will be painted along with other repairs on the structure.  

 

During the nine-month project, traffic across the bridge will be controlled by signals at either end, with only one direction allowed to pass through at a time. Under normal conditions, the delays are expected to be 15 to 45 minutes in length. In addition, a nine-foot width restriction will be in effect.

 

RSCI, of Meridian, is the contractor on the $2.8 million project.

 

CANYON COUNTY

NAMPA City traffic signal synchronization

A project began on Jan. 3 to link traffic signals to create a more efficient traffic flow in and around downtown Nampa.

 

This six-month project will allow traffic signals to be synchronized through fiber optics and will add pedestrian signals with countdown indicators at intersections. The signal improvements will mean people who drive the posted speed through the area should have fewer stops for red lights.

 

The work will be done primarily on 2nd and 3rd Street South and on 12th and 16th Avenue South. Signals on 7th Street South also will be included, as will the signal at 1st Street South and 11th Avenue South.

 

The contractor has drilled and installed conduit down 12th Avenue from 7th Street to 5th Street. Crews are now starting to drill and install conduit down 12th Avenue from 5th Street to 3rd Street. There are intermittent lane closures on 12th Ave (Idaho 45) from 8:30 a.m. to 4 p.m. for equipment storage and utility exploration. 

 

All the work so far is underground, through a 2-foot by 3-foot access hole.

 

There will be intermittent lane closures on 16th Avenue and 12th Avenue (Idaho 45) during non-peak hours for equipment storage and utility exploration.

 

Construction crews will try to limit closures to sidewalks and parking stalls in the work areas. The contract does allow for lane closures if necessary, but only between the hours of 8:30 a.m. and 4 p.m.

 

Quality Electric Inc., of Boise, is the construction contractor on this $1.01 million project. The city of Nampa paid for the design on this project and will pay a portion of the construction contract cost. No ITD funds are being expended on this off-system project. The funding breakdown is almost 93 percent Federal Aid and just over 7 percent Local funding. ITD is involved as a steward of the federal aid monies.

 

ELMORE COUNTY

MOUNTAIN HOME Canyon Creek Bridge replacement

Replacement of the old, narrow Canyon Creek Bridge is under way. The bridge is located near milepost 9 on Canyon Creek Road, north of Mountain Home.

 

The road, which sees a fair amount of hunting-related traffic each fall, will be completely closed through late January.   

 

The detour route will start at the intersection of Canyon Creek Road and Frontage Road, and continue west past the Sunset Highway on Old Oregon Trail Highway. The detour will cross I-84 to the north at Ditto Creek road and continue along Martha Avenue to the east, back to Canyon Creek.

The bridge replacement also involves minimal approach work to the connecting roads to ensure that the bridge and road fit together seamlessly. The bridge also will include guardrail (railing), which the old bridge lacks.

 

The contractor is working on the roadway approaches.

 

The Mountain Home Highway District is the local sponsor of the project.

 

McAlvain Contractors, of Boise, is the contractor on this $493,000 project.

 

PAYETTE COUNTY
PAYETTE U.S. 95, Payette River Bridge replacement

The project to improve the U.S. 95 bridge over the Payette River south of Payette is now under way. It is expected to take about two years to complete, finishing in fall 2012.

Crews will replace the existing northbound truss bridge (built in 1927) located on U.S. 95 between Fruitland and Payette. The new bridge will be two feet higher off the water. It will have no overhead bracing or struts as the current one does and will be 84 feet in width, eliminating current safety concerns regarding both width and height restrictions.

The new bridge will be constructed next to, and will attach to, the existing southbound bridge. The project also includes minor roadway realignment to tie into the new bridge location.

U.S. 95 is the main route connecting northern and southern Idaho. About 18,000 vehicles use this portion of the highway daily. By 2026, the volume is expected to be more than 25,000.

Traffic will utilize the southbound bridge while the new bridge is constructed. Traffic will then be switched to the new bridge while modifications to the southbound bridge are made and it is connected to the new bridge.

 

JC Constructors Inc., of Meridian, is the contractor for this $6.17 million project.
