Southwest Idaho highway construction report for Dec. 4-11
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,
Orchard Street Interchange
Work continues on a project to reconstruct the Orchard Street Interchange
in Boise.
The speed
limit on I-84 is 55 mph and shoulders are restricted in the project area. The
speed limit on surrounding roadways (Orchard Street, Wright Street, Victory
Road) is 25 mph. ITD advises motorists to be cautious of trucks and equipment.
Construction
is expected to be complete in spring 2010.
BOISE - Interstate
84, Vista Avenue Interchange Reconstruction*
Work is under way to rebuild the Vista Avenue Interchange to
reduce congestion and accommodate future I-84 lanes.
Demolition of the old Vista Interchange bridge continues
through Sunday morning (Dec. 6). I-84 under the overpass will be closed from 10
p.m. until 7 a.m. Flaggers will detour traffic using the off- and on-ramps.
The speed limit on I-84 is 55 mph. Watch for trucks entering
and exiting the construction zone.
Construction is expected to be complete in fall 2010.
* Design for the project was funded by GARVEE, but project construction is funded through the federal stimulus program, created to generate jobs and help boost Idaho's economy while upgrading our foundation for future economic growth.
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.
One westbound lane will be closed near the Orchard Interchange nightly from 10 p.m. to 5 a.m. Crews are widening the shoulders, and work continues through Tuesday morning (Dec. 8).
The speed limit is 55 mph in the project area on I-84.
This project is expected to be complete in summer 2011.
WEST TREASURE VALLEY - Interstate 84,
Garrity to Meridian widening
ITD has added a third east- and westbound lane to I-84
between Nampa and Meridian.
Between Black Cat and Ten Mile roads, the third lane will
remain closed until spring 2010 during work on the Ten Mile Interchange.
The I-84
speed limit is 55 mph during construction.
MERIDIAN - Interstate 84, Ten Mile
Interchange construction
Work continues on a project to replace the current Ten Mile
Overpass with an interchange with on- and off-ramps. This project includes
widening Ten Mile Road and constructing two undercrossings for local roads
north and south of I-84.
Daily pile driving continues throughout the month of
December. Pile driving hours are 7 a.m. to 9 p.m. Work will be done six days
each week at the site of the future Ten Mile Interchange. It is the final
location for pile driving.
The Ten Mile Overpass will be demolished on the night of
Dec. 11. I-84 will be closed between the Meridian and Garrity interchanges from
10 p.m. Dec. 11 to 7 a.m. Dec. 12. Flaggers will detour interstate traffic to
Franklin Road during demolition. Motorists should watch for heavy equipment in
the construction area.
Ten Mile Road will be closed between Franklin and Overland
roads starting Dec. 11. It will remain closed until summer 2011. Alternate
routes have been posted on itd.idaho.gov to guide motorists around the closure.
Signs will be posted near Ten Mile Road.
The speed limit has been reduced to 35 mph on Ten Mile Road
between Franklin and Overland roads. Motorists should watch for trucks
traveling in the area.
Construction is expected to be complete in summer 2011.
In
addition, this GARVEE project will begin soon:
NAMPA - Interstate 84, Garrity Interchange Bridge reconstruction
ITD will replace two bridges in the Garrity Interchange with
a single, wider bridge to support additional lanes on the interstate. The
project will construct a third east- and westbound lane on I-84 through the
Garrity Interchange.
Est. Start: January 2010
Est. Completion: Summer 2011
Following is an update on non-GARVEE state highway construction projects in southwest Idaho.
WEISER - Snake
River Bridge replacement
The Snake River Bridge on the U.S. 95 Spur in Weiser is being replaced with a
wider structure. The bridge connects Annex, Ore., to Weiser.
The concrete decking for the new bridge was poured overnight this past week (Dec. 1-4).
The right and left ramps on the Idaho side of the bridge are closed. Traffic must follow the detour to access Old Highway 70. In addition, any traffic 12 feet or wider and/or taller than 14 feet 2 inches will need to detour through Payette.
Both abutments on the Idaho side of the bridge have been finished.
The original bridge was built in 1903, with an additional span added in 1911. Traffic signals were added in 1949. The bridge was replaced in the 1950s - that's the one being replaced in this project. Once completed, the bridge will be 16 feet wider and able to carry greater traffic volumes. The highway on both sides of the bridge also will be reconstructed.
New curb, gutter and sidewalks are being reconstructed on the Idaho side of the bridge.
The speed limit 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 may extend into spring 2010.
ITD and the Idaho State Police caution motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Motorists are encouraged to plan ahead and dial 5-1-1 or visit 511.idaho.gov for information on the state highway or interstate system.
