ODOT and consultant recommend medians, R‑cuts and targeted fixes to reduce crashes on State Highway 9
Summary
A Freese and Nichols safety study for the Oklahoma Department of Transportation covering State Highway 9 from 48th to 120th Avenue found just over 100 collisions from 2017–2022 (including about six fatalities) and recommends access management—continuous medians, R‑cuts and spaced U‑turns—paired with near‑term lighting, signage and turn‑lane improvements.
Kayla Byrd, a consulting engineer with Freese and Nichols, presented a road‑safety study to the City Council Community Planning and Transportation Committee on March 26 that examined a six‑mile section of State Highway 9 from 48th to 120th Avenue and identified both long‑term and near‑term strategies to reduce crashes.
The study reviewed five years of collision data, updated traffic counts and multiple field reviews and found "just over 100 collisions" from 2017–2022 with a concentration at intersections, and "about six" very severe collisions or fatalities during that period, Byrd said. The most common crash types were right‑angle and turning crashes tied to frequent access points and the corridor’s higher travel speeds, which Byrd said tend to be in the 60–65 mph range.
The consultant’s recommended long‑term approach (Alternative 1) centers on access management: a continuous grass median from 48th to 108th, R‑cuts (restricted crossing U‑turns) at side streets to remove direct crossing/left‑turn movements, and designated U‑turn locations spaced…
