I-84 Bridge repair in Caldwell at Black Canyon
A project to rehabilitate and repair bridge decks in the Caldwell area and at Black Canyon on Interstate 84 is expected to begin early this summer.
Decks on bridges at these locations (year built listed in parenthesis) will be addressed between the end of May and late August:
• The Centennial Way overpass (Idaho 19) in Caldwell (1983) – The top few inches of the existing surface will be removed and a concrete overlay added. The sidewalks will be waterproofed.
• The eastbound off- and westbound on-ramp over the Boise River at Caldwell’s Exit 27 (1980). The top few inches of existing surface will be hydro-blasted (removed with a high-pressure water stream), and a silica fume overlay (filler to improve concrete strength and density) will be added. The same work will be done on the next bridge.
• The I-84 crossing over the Boise River in Caldwell (1983).
• The bridge over I-84 at Black Canyon’s Exit 13 (1960). This work will be more extensive. Crews will rebuild the south side of the approach to the bridge, replace guardrail, overlay all of the ramp approaches, repair girder ends and replace pier bearings, hydro-blast the deck, place new expansion joints, add a silica fume overlay and apply waterproofing to the curb(s).
No weekend work is anticipated, but is allowed if needed.
Concrete Placing Co. Inc., of Boise, is the apparent low bidder on the $1.42 million project.

U.S. 95 Parma-Wilder resurfacing
A stretch of U.S. 95 from the south city limits of Wilder to the south city limits of Parma, and from the north side of Parma to the junction with Interstate 84 will be resurfaced in a project starting in mid-May.
In all, about 23 miles of the route will be resurfaced, repaired and widened in areas during the three-month project.
• 13.2 miles of U.S. 95, from Parma north city limits to Jct. I-84
• 1.6 miles of U.S. 20/26, from Snake River Bridge to Jct. U.S. 95
• 8.2 miles of U.S. 95, from Wilder south city limits to Parma south city limits
In two-lane sections, at least one lane will remain open at all times. In three- or four-lane segments, at least two lanes will remain open.??Work on nights or weekends is not expected, but is not prohibited if needed.
Idaho Sand & Gravel Co., of Nampa, is the contractor on this $5.7 million project.
PAYETTE COUNTY
FRUITLAND – U.S. 95/I-84 Exit 3 Overpass repair
Work is under way to resurface and repair the half-century-old U.S. 95 interchange overpass spanning I-84 at Exit 3 near Fruitland. The project is expected to finish in June.
The bridge deck and foundation for this bridge are considered to be in fair condition, with the superstructure in good condition.
The concrete deck will be overlayed and pier caps and columns patched in this project to extend the life of the bridge, built in 1960. The bridge railing will also be replaced.
Asphalt paving work will be performed to tie the bridge approaches into the road on each end of the bridge.
The normal lane, shoulders, and center lane are reduced slightly and allow passage of 14-foot vehicle and cargo widths.
A full-width deck removal between the two center girders has been completed down the length of the bridge. Forms have been fitted to allow replacement of this center section of deck. Crews are preparing areas to be patched on the abutments, columns and piers.
Cannon Builders Inc., of Blackfoot, is the contractor for this $763,000 project.
PAYETTE COUNTY
PAYETTE – U.S. 95, Payette River Bridge replacement
The project to improve the U.S. 95 bridge over the Payette River south of Payette is under way. It is expected to finish in mid-September 2012.
Crews are replacing the existing northbound truss bridge (built in 1927) located on U.S. 95 between Fruitland and Payette. The new bridge will be two feet higher off the water. It will have no overhead bracing or struts, as the current one does, and will be 84 feet in width, eliminating current safety concerns regarding both width and height restrictions.
The new bridge will be constructed next to, and will attach to, the existing southbound bridge. The project also includes minor roadway realignment to tie into the new bridge location.
U.S. 95 is the main route connecting northern and southern Idaho. About 18,000 vehicles use this portion of the highway daily. By 2026, the volume is expected to be more than 25,000.
Forms and reinforcements for two spans of the new bridge deck were completed last week. Crews continue removing the northbound section of concrete bridge deck, and have about one-third of the deck left to go. Bridge girders are being jacked up to replace bearing pads in the two center spans of the bridge. They plan to pour the southbound section in mid-April.
JC Constructors Inc., of Meridian, is the contractor for this $6.17 million project.
