Construction set to begin Sunday (Jan. 10) at I-84 Garrity Interchange in Nampa
BOISE
- Construction on the I-84 Garrity Interchange improvement project in Nampa is anticipated
to begin Sunday, (Jan. 10).
Crews will begin placing traffic barrels for the Idaho Transportation Department project and installing advanced warning signs on Sunday night. Trucks and heavy equipment will begin working in the area on Monday (Jan. 11).
Later this month, lane restrictions are anticipated to begin on Garrity Boulevard. At least one lane in each direction will be open on Garrity during daytime hours. Drivers can expect two lanes open in one direction and one lane open in the opposite direction during some of the construction. Many times, two lanes will be open in each direction. The speed limit will be lowered to 35 mph on Garrity and 55 mph on I-84 through the construction zones.
The project will remove two bridges on I-84 at the Garrity Interchange and replace them with a single bridge that will accommodate three lanes in each direction on the interstate. 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.
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 four lanes in each direction from the Garrity to Meridian interchanges.
The project will be constructed in three stages:
Stage 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.
Stage 2 - Remove existing westbound bridge and build new westbound portion of
bridge. Westbound traffic will be moved onto the new median section. Two lanes
will remain open in each direction.
Stage 3 - Remove existing eastbound bridge and build 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 of the
$15 million project.
This work is funded
through the GARVEE Transportation Program, which uses Grant Anticipation
Revenue Vehicle (GARVEE) bonds to expedite interstate improvements.
