JEFFERSON COUNTY, Mo. (Oct. 7, 2025) — So far in 2025, state and local sources report approximately 30 crashes on Interstate 55 in Jefferson County, a stretch currently undergoing construction improvements. The confluence of aggressive driving, speed, and distracted behavior has officials urging motorists to heed caution in work zones, especially on I-55.

One of the most serious occurred Sunday afternoon Sept. 28 south on the Festus exit when a semi‑tractor trailer struck a slower vehicle in a work zone, triggering a chain‑reaction crash involving eight vehicles. Three people died and five others were injured.

Just a week later on another Sunday afternoon Oct. 5, a three-vehicle crash occurred in the same area as the crash on Sept. 28. The Missouri State Highway Patrol stated on the crash report that, similar to the Sept. 28 fatal crash, a 2024 Ram 2300 failed to slow down for vehicles already slowed due to congested traffic and crash into them.

Another crash July 14 involved three vehicles south of Route M; four people were transported to the hospital with varying injuries.

A separate incident March 15 just north of Route M saw a Farmington man’s vehicle rear‑end another car that was blocking a lane; the driver suffered moderate injuries.

Among more recent events, a three‑vehicle crash Sept. 21 south of Imperial Main Street was blamed on one driver failing to stop in slowed traffic, pushing a vehicle into a barrier and causing a secondary impact. One person was hospitalized.

State highway patrol and local traffic safety officials say the I‑55 construction corridor has become a high‑risk zone, especially when speed and driver inattention coincide. With lane shifts, narrowed shoulders, and altered traffic patterns, even minor lapses in attention can result in serious collisions.

Missouri’s work‑zone crash history provides broader context: in 2024, the state recorded 350 crashes in construction zones. Distracted driving was cited as a top contributing cause.

Under Missouri’s Siddens‑Bening Hands‑Free law (effective Jan. 1, 2023 enforcement), use of handheld phones while driving is prohibited. Yet in work zones, where conditions change rapidly, even hands‑free or brief glances at devices can be enough to derail control.

Research supports the danger: even in professional work zones protected by truck‑mounted attenuators, distracted or inattentive drivers may fail to recognize warning signs or respond in time.

Further complicating the picture, speeding remains a persistent issue. Multiple crash narratives reference drivers closing distance too quickly when traffic slows — a classic recipe for rear-end and multi-vehicle collisions in congested or construction-adjusted settings.
