City of Lewiston Invites Public Input on East Lewiston Transportation Network Analysis, Idaho Open House Set for May 12
Lewiston Residents Asked to Weigh In on Long-Range Road Planning Effort
The City of Lewiston is inviting residents to participate in an informational open house focused on the future of transportation infrastructure in the eastern portion of the city. The event is scheduled for Tuesday, May 12, 2026, from 4:00 p.m. to 6:00 p.m. in the Commons at Lewiston High School, located at 3201 Cecil Andrus Way, Lewiston, Idaho.
The open house is centered on the East Lewiston Transportation Network Analysis (ELTNA), a long-range planning effort designed to establish a blueprint for future arterial and collector roadways in northeast Lewiston. The study area is generally bounded by Gun Club Road, Lindsay Creek Road, and Warner Avenue — a corridor expected to experience significant growth and development pressure in the coming years.
City officials say the project will help guide responsible growth while maintaining safe and efficient traffic flow throughout the region. The plan is also intended to support coordination between the City of Lewiston, Nez Perce County, and private developers to help phase roadway construction as new development occurs — a fiscally responsible approach that ties infrastructure investment to actual development activity rather than speculative expansion.
For residents unable to attend in person, a digital open house is available from May 1 through May 12, 2026, at arcg.is/0H1CbK0. The online format allows community members to review proposed roadway connections and submit feedback on their own schedule.
Building on Prior Congestion Studies Along Key Lewiston Corridors
The ELTNA project does not start from scratch. It builds directly on findings from a previous study, the Thain Road Corridor Study and Access Study, adopted under Resolution 2024-43, which identified that key routes — including Thain Road, 21st Street, and Bryden Avenue — are already experiencing congestion. That earlier study flagged the need for a broader network-level response before additional development compounds existing traffic problems.
ELTNA takes that analysis a step further by mapping out where future traffic will travel before new development adds additional demand to an already-strained system. Planning transportation networks ahead of growth, rather than reacting to it after the fact, is a cost-effective strategy that can reduce the long-term tax burden on residents by avoiding expensive emergency road upgrades down the road.
The project is funded by the City of Lewiston and led by engineering consultants Kittelson & Associates. City officials have not released specific cost figures for the planning effort in publicly available materials.
The open house on May 12 will give attendees the opportunity to learn about proposed roadway connections, ask questions of project team members, and provide direct input on how the plan takes shape. Public participation in long-range planning efforts of this kind is considered an important part of ensuring that infrastructure decisions reflect the needs and priorities of the community being served.
Lewiston has seen a number of infrastructure-related initiatives in recent months. The city recently received a significant environmental funding award, with Idaho DEQ awarding $1,800,000 to the City of Lewiston for related improvements. Separately, night construction work began on the Snake River Avenue project in April, underscoring the pace of ongoing infrastructure activity across the Lewis-Clark Valley.
Residents are encouraged to attend the May 12 open house or participate digitally before the comment window closes. The City of Lewiston has not announced additional public input opportunities beyond this event and the digital portal at this time.
What Comes Next
Following the May 12 open house and the close of the digital comment period, project engineers at Kittelson & Associates are expected to incorporate public feedback into the ELTNA planning framework. The resulting transportation blueprint will guide future coordination between the City of Lewiston, Nez Perce County, and developers as the northeast Lewiston area continues to grow. No timeline for a final plan adoption has been publicly announced.
