Public Online Meeting

Project overview and background

The Idaho Transportation Department is constructing a new State Highway 52 Bridge in Payette over the Snake River, which connects Idaho and Oregon.

Built in 1953, the 72-year-old current bridge no longer meets modern highway bridge standards for motorists, including freight haulers who transport produce across the region.

The bridge barriers, width, and surface will be improved in coordination with the Oregon Department of Transportation.

Construction phasing

ITD and ODOT heard from emergency responders, freight haulers and the community that a full closure would not be feasible during construction and could impact response time and access.

In response, bridge construction will be in two steps, meaning a new bridge will be constructed one-half at a time.

Construction will take approximately two years.

Staging location

During construction, materials and equipment will be staged at the north end of Centennial Park. This will allow for efficient construction of the bridge.

ITD is working with the City of Payette to minimize disruptions and maintain public access to the south end of the park and the widely used boat ramp.

Temporary construction structure

Before the bridge is constructed, crews will install a temporary structure to help workers and machines work safely and efficiently. The structure will act as a work platform that will be removed once the bridge is finished.

Step 1 construction

The existing bridge will remain fully open and there will be no change for the traveling public. The first half of the new bridge will be built just north of and next to the old bridge. One lane of traffic will remain open in each direction during construction, except for limited closures. We anticipate this construction step will take about one year to complete.

SH-52 Snake River Bridge typical cross section of Phase 1, 2 and the Final Section. Phase 1 includes SH-52, the existing SH-52 & Bridge, a section showing the construction with half of the new bridge in phase 1, intermittent lane closures, and a note to maintain the existing 2 lanes with intermittent lane closures.

*Durations subject to change

Step 2 construction

The bridge crossing will be down to one lane. Temporary traffic signals will allow traffic to alternately travel one direction at a time. Traffic can expect some travel delay. Information will be publicized as construction nears. We anticipate this construction step will take about one year to complete.

Phase 2 includes SH-52, noting that temporary traffic signal will allow one direction at a time, Phase 2 Construction, closure pour and complete remaining bridge. the Final section includes two 12-foot lanes, two 8-foot shoulders, and a new deck and guardrail.

*Durations subject to change

Bridge design details

The new bridge will include:
