Construction Updates

   

Traffic Impacts: November-December 2008

 

Meridian Interchange to Ten Mile Overpass, Nov. 16-29*

  • The I-84 westbound shoulders will be closed.
  • Traffic entering westbound I-84 at the Meridian Interchange will use a dedicated lane for about 2.5 miles and will merge just west of Ten Mile Overpass.
  • *Dates are approximate and may change depending on weather.

Nov. 29 (Saturday night): I-84 westbound lanes between the Meridian Interchange and Black Cat Road will be shifted onto the newly reconstructed pavement. ITD reminds motorists to use extra caution while traveling this area.

  

In mid-December, eastbound traffic from Garrity to Meridian will be shifted onto the new pavement in the median while old eastbound lanes are reconstructed.

 

Please plan ahead for the following traffic impacts on I-84 between Garrity Boulevard Interchange and Locust Grove Overpass:

 

Summer 2008-2010:

  • The speed limit is 55 mph.
  • Shoulders are restricted.
  • Two lanes in each direction are open during the day.

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).
    

Project Facts

   
MP 37.945-44.38
Project Number: A010(459)
Key Number: 10459
    

Description

   
The Idaho Transportation Department (ITD) is widening and reconstructing 6.2 miles of I-84 between the Garrity and Meridian interchanges.  ­­When complete, the new six-lane divided interstate will reduce congestion and improve safety for motorists. ITD is constructing a third lane in each direction in the existing median. A permanent barrier will be placed between the east- and westbound lanes. 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. 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.
