Southwest Idaho highway construction report for Jan. 19 - Jan. 26
BOISE - Following is an update on highway construction projects in southwest Idaho.
ADA COUNTY
Blacks Creek Rest Area
Western Construction is the contractor on a $10.2 million project to rebuild this Interstate 84 rest area, located about 10 miles east of Boise. There is a rest area for eastbound traffic and one for westbound traffic. When finished, the rest areas will include new bathrooms, a picnic area with tables and seating and new landscaping. All eastbound and westbound lanes are open as they pass the construction area. Remaining work is taking place away from interstate lanes and is on the rest areas' grounds.
Locust Grove Overpass
Work started in December on a new overpass that will connect Locust Grove Road and offer an extended route over Interstate 84 between Eagle Road and Meridian Road. Currently, Locust Grove Road south of Interstate 84 ends near the interstate. The north side of Locust Grove Road also ends near Interstate 84. The new overpass, scheduled to be finished in the spring of 2008, will consist of two lanes in each direction, sidewalks and bike lanes on both sides of the overpass. Utility and irrigation work started in early December, and will continue through January and February. Construction on the overpass will start in the spring. Minimal impacts to traffic are anticipated during construction. Girders, placed during the night-time hours, may reduce interstate traffic to single lanes. Concrete Placing Company Inc. of Boise is the contractor for the $5,845,000 project.
CANYON COUNTY
Interstate 84, Franklin Interchange, Caldwell
The Franklin Road Interchange is being reconstructed to improve access to Caldwell from I-84, improve traffic flow, and ease congestion. The project, which started in early December, will enhance several aspects of the interchange. The current two-lane Franklin Overpass will be replaced with a six-lane bridge. The new overpass will have two through lanes in each direction and dual left turn lanes in each direction. The interchange ramps will be lengthened and widened to two lanes at their intersection with Franklin. Traffic will use temporary interstate on- and off-ramps while the old ramps are rebuilt. Franklin Road will be widened from two to five lanes between the overpass and Specht Avenue. The new road will have a curb, gutter, sidewalk, bicycle lanes and shoulder. Aviation Way will be widened at the intersection with Franklin Road. A new traffic signal also will be added. Lanes may be reduced temporarily on Franklin Road and Aviation Way during the widening. Both roads will remain open during construction. One or both lanes of I-84 may be closed between 7 p.m. and 5 a.m. for safety while crews replace the overpass. Traffic will be detoured. A new bridge and three new lanes will be constructed before the old overpass is torn down and traffic will use the new three lanes while crews replace the old bridge. At the project's completion, all six new lanes will be opened. Traffic updates will be posted to ITD's 511 service (511.Idaho.gov, or dial 511). Concrete Placing Co. is the contractor for the $25 million project. Construction is scheduled to be finished in the fall of 2008.
Idaho 55, Marsing to Sunnyslope Curve
The road will be widened to five lanes with guardrail, irrigation, drainage facilities and a new canal bridge added in this three-mile section of Idaho 55. Motorists will be assisted through the work zone by traffic control devices and flaggers. The speed limit is reduced to 45 mph in the work zone. Access to Sunnyslope Road (Idaho 55) from Pear Lane closed on Dec. 18 to allow crews to build a new bridge over the Low Line Canal. The alternate access route to the south is at Apricot Road using Frost Road. The alternate access to the north is Hoskins Road using Frost Road. Both alternate routes will be signed as detours. The closure is expected to last until late February. Idaho Sand & Gravel is the contractor for this $6.1 million project that will be finished in spring 2007.
During the fall and winter months, the Idaho Transportation Department advises motorists to monitor road conditions by visiting 511.idaho.gov or calling 511.
