BOISE - Interstate 84, Orchard Street Interchange
Work continues on a project
to reconstruct the Orchard Street Interchange in Boise.
Motorists
will begin driving on the new Orchard Street Bridge in mid-October. The old
bridge will be demolished in late October.
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.
Between 10 p.m. and 5 a.m. Thursday through Saturday (Oct. 8-10) at least one lane will be open in each direction on I-84 near the Orchard
Interchange while crews work on the bridge deck.
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.
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.
Between 10 p.m. and 5 a.m., Thursday through Saturday morning (Oct. 8-10), at least one lane will be open in each direction at night on I-84 between the Cole and Orchard interchanges while crews install guardrail, place sand barrels and remove lights.
The speed limit is 55 mph in the project area on I-84.
This project is expected to be complete in summer 2011.
ITD is adding a third east- and westbound lane to I-84
between Nampa and Meridian. The first 2.5 miles of the third lane opened near
the Meridian Interchange in August 2009. The remainder is expected to open in
late October 2009.
Westbound I-84 will be reduced to one lane from 10 p.m. Sunday to 5 a.m. Monday during the shift.
The I-84
speed limit is 55 mph during construction.
Work began in late July 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.
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 in the fall:
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: Late Fall 2009
Est. Completion: Winter 2010
Working hours are primarily 7 p.m. to 6 a.m. Sunday through Thursday to
minimize interference with traffic. However, they may be extended for
the last few weeks of the project due to inclement weather.
The pavement in this stretch is rough and rutted. The resurfacing process will
extend the life of the roadway and create a smoother ride for motorists.
About an inch and a half of the existing pavement is being milled off the
surface, then replaced with new material in an overlay.
The 5.5-mile corridor shifts from as few as two lanes to as many as six. At
least one lane in each direction will be maintained throughout the project. The
traffic pattern for the corridor will change several times throughout the life
of the project.
Knife River of Boise is the contractor for this $1.4 million project.
CANYON COUNTY
CALDWELL - Indian Creek Bridges replacement
Two
companion projects to improve the structural integrity of two bridges over
Indian Creek is moving into the final weeks and is scheduled for completion in
November. The projects to replace bridges at 21st and 11th
Avenue started in June.
Crews at 11th Avenue and Arthur will complete work on the abutments for the new bridge this weekend. Once the new abutments are in place the dams and pumps that diverted water from the creek during construction will be removed making for a much quieter work zone. Vehicles continue to be detoured around the intersection but pedestrian access to local business remains open and signs are in place to direct customers.
Work at the 21st Avenue bridge is progressing and crews have set the stringers that will be the supporting backbone of the second half of the new bridge. Work to place the new deck will begin in the next week. Traffic remains shifted to the new half of the structure while work to finish the deck on the second half of the bridge is completed.
Removal
of the existing 21st Avenue bridge and construction of the new concrete bridge
is being completed in two phases. During the first phase, the east portion of
the bridge was removed and reconstructed, and traffic was routed onto the
existing bridge. During the second phase, traffic has been shifted to the
completed portion of the new bridge while the other half is reconstructed.
When construction is complete the new bridge will have four lanes (two lanes in each direction) to better serve the well-traveled route between Interstate 84 and The College of Idaho. Two lanes of traffic are being maintained during construction and business access on 21st remains open. Temporary signs are in place to direct customers.
Braun-Jensen of Payette is the contractor on this $2.3 million project. This is a Local Highway Technical Assistance Council project sponsored by the city of Caldwell.
The old bridge was removed Aug. 5 and work has begun on
the new bridge.
The roadway ballast section is constructed, and concrete work
(sidewalk, drop inlets, curbs) should be completed. Work on the bridge back
wall and sidewalk is expected to be completed in a few weeks.
