I-84 Garrity Interchange to Meridian Interchange

   
  
 

Construction Updates

   

Traffic Impacts


Motorists are advised to use caution when heading westbound on I-84 near the Meridian Bridge.  Construction trucks will be merging with traffic in this area.


Summer 2008-2010:

  • The speed limit is 55 mph.
  • Shoulders are restricted.
  • Two lanes in each direction are open during the day.
  • Brief ramp closures are expected on occasion.

At least one lane is open in each direction at night (10 p.m. to 5 a.m. on weekdays, 10 p.m. to 7 a.m. on weekends).
    

Description

   
When complete, the new six-lane divided interstate will reduce congestion and improve safety for motorists.

This project requires reconstructing the existing Robinson and Black Cat bridges to accommodate additional lanes on I-84.

Widening work will allow for a fourth lane in the future. Additional environmental work, traffic analysis and overpass widening are needed before the fourth lane can be completed.
    

Background

   
The 2001 I-84 Corridor Study by the Community Planning Association of Southwest Idaho (COMPASS) and ITD recommended widening I-84 between Garrity Boulevard and Meridian Road.
    

Schedule and Funding

   
Construction has begun and is expected to be complete in fall 2009. The construction scheduled has been shortened by 6-8 months by using phased contracting on this project. Accelerated construction practices save taxpayer dollars by increasing competition and averting escalating costs.

Phased construction contracts include:

Ten Mile Creek
January-April 2008: Build a new drainage structure in the median over Ten Mile Creek.

Milling Work
January-April 2008: Mill the road to remove ruts and prepare for construction-related traffic shifts.

Ten Mile Overpass to Meridian Interchange
June 2008-Summer 2009: Construct new lanes.
Spring 2009: Modify Meridian Interchange loop ramp to allow for additional lanes on I-84.

Garrity Interchange to Ten Mile Overpass
Summer - Fall 2008: Prepare median for construction of new lanes.
Fall 2008 - Fall 2009: Construct new lanes.

Stormwater Ponds
August-November 2009

Construction is funded through the GARVEE Transportation Program. The program uses Grant Anticipation Revenue Vehicle (GARVEE) bonds to expedite interstate improvement.
