Construction Begins On I-15 Business Loop

IDAHO FALLS – Construction on the Snake River and Porter Canal bridges on the Interstate 15 business loop (Broadway Street) in Idaho Falls will begin at 10 p.m. Tuesday (Sept. 29).

Crews will repair joints and install new pedestrian railing on the bridges, and resurface sidewalks on the Porter Canal Bridge.

Workers also will sandblast and paint the ends of steel girders on the west side of the Snake River Bridge. The work will enhance bridge safety and longevity.

The maintenance is scheduled for completion in mid-October.

During construction, which will be mostly at night in Idaho Falls to minimize inconvenience for motorists and pedestrians, travel will be reduced to two lanes in each direction, and sidewalks will be closed.

As part of the bridge-preservation project, crews also are refurbishing the Great Western Canal Bridge on I-15 about three miles north of Idaho Falls, resurfacing the deck with high-strength concrete and performing other maintenance. Work is scheduled for completion in mid-November.

The transportation department awarded the $1.2 million contract for the bridge work to Cannon Builders Inc., of Blackfoot.
