Staff recommend lower citywide speed limits after pilot cuts high‑end speeding 20–40%

Bellevue transportation staff on Jan. 27 presented results from evaluation corridors and a recommended citywide safe‑speeds framework designed to reduce serious injuries and fatalities.

John Murphy reported that lowering posted speeds on four corridors produced roughly a 20–40% reduction in high‑end speeding — the subset of speeding most associated with severe crashes. "Through just changing the signs on these 4 corridors we saw a, roughly 20 to 40% reduction in high end speeding," Murphy said.

Benjamin Wright explained the staff methodology for setting safe speeds: each corridor is assessed for levels of “activity” (land use density, transit, on‑street parking) and “conflict” (intersections, midblock crossings, driveways). Where activity and conflict are high, staff generally recommend a 25 mph limit; in sections adjacent to Downtown Park and Old Bellevue staff proposed 20 mph zones. Where activity and conflict are low, staff suggested a higher limit (up to 35 mph) remain.

Staff outlined a phased implementation (starting with the urban core and high‑injury network), expanded signage, signal timing adjustments and complementary tools such as radar signs, speed safety cameras and traffic calming measures (speed cushions, raised crosswalks). Staff will continue outreach and return to council with draft speed limits for formal action in June.

What to watch: staff will refine the proposed lines and implementation plan, coordinate with neighboring Redmond where centerlines straddle the jurisdictional border, and align enforcement priorities with Bellevue Police Department initiatives to focus on egregious speeding and racing.
