Springfield council reviews Gateway transportation options as 2029 TSP deadline approaches

Grama Newman, Springfield’s transportation planning manager, told the City Council that the city must complete a major Transportation System Plan (TSP) update by 2029‑12‑31 under the state’s updated transportation planning rules and invited council guidance on how to address chronic congestion and safety problems at the I‑5/Beltline gateway.

Why it matters: the gateway area has long been identified in city and state planning as a congestion and safety problem. Newman said the city’s model and plan must show per‑resident reductions in vehicle miles traveled and include a financially constrained project list, requirements that will shape which projects the city can pursue.

Newman summarized past planning: the original interchange at I‑5 and Beltline was built in 1968, ODOT implemented a safety project in 1999 and a 2003 revised environmental assessment (EA) evaluated three alternatives for the interchange and surrounding area. The EA produced an Interchange Area Management Plan (IAMP) with two phases; Phase 1 has been built, but the Phase 2 couplet project has not. Newman said an implementation intergovernmental agreement intended to trigger Phase 2 expired in 2008 and that informal follow‑up between city and ODOT staff did not lead to construction.

Newman warned that building the couplet as described in the EA would require relocating multiple businesses, including gas stations, a convenience store and Hop Valley Brewery. She noted ODOT shared that the planning funds the agency offered to support Springfield’s TSP update would require a 10.27% city cash match and do not include funds for an IAMP amendment. "ODOT is bringing some money to the table to help with our major TSP update, but the city will need to provide a 10.27% cash match for that process," she said. Newman added that pursuing an interchange area management plan today would require "about one‑and‑a‑half million or so or more in today’s dollars," a planning‑scale cost that would require additional resources.

Staff outlined three broad approaches: build the plan projects including Road R‑50 and the couplet; change the planned projects (or accept an alternative mobility standard that accepts more congestion at specific locations); or use a combination of both. Newman said there is no low‑cost, immediate fix that solves every problem and that additional consultant support and multi‑year effort will be needed if the city wants to move beyond the TSP‑required work.

Councilors pressed staff on measurement and sequencing. When asked how the required reductions are calculated, Newman said the work uses a transportation and land‑use model and that vehicle‑miles‑traveled reductions are measured per resident in Springfield. Michael Liebler, the city’s transportation planning engineer, told the council that development applications currently rely on the couplet project in the modeling to meet level‑of‑service findings: "When you plug in that couplet project, it provides the additional capacity that allows [developers] to continue with their development," he said. Liebler added the city has not established a reimbursement district for the area and generally relies on system development charges rather than project‑specific exactions.

Several councilors said they favored revisiting plan assumptions rather than simply advancing the EA’s couplet without modification. Councilor Rodley said, "I think I'm leaning towards option B of changing plans," and urged the council to dig in now rather than defer work. Others asked staff to identify low‑cost, high‑impact safety fixes and to provide better cost and staffing estimates to compare in‑house capacity versus hiring consultants.

What’s next: staff are seeking direction from council on whether to pursue plan changes, fold North Gateway work into the next major TSP update, or adopt a refinement pathway in the TSP requiring later detailed plans. Newman said staff will return with more detailed scope and cost options and warned that any work beyond the mandated TSP update will require dedicated funding and consultant support.
