Construction Zones & Detours: Staying Safe on St. Louis Roads
St. Louis interstate loops see near-constant construction projects, and construction zones are where a routine commute can turn into a stressful, high-risk stretch of road if you’re not prepared.
What Makes Construction Zones Riskier
- Narrowed lanes with less room for error
- Sudden merges that catch drivers off guard, especially at night
- Reduced or shifted shoulder space if you do need to pull over
- Uneven pavement transitions that can stress tires and suspension
How to Drive Through Them Safely
Slow down to the posted construction speed well before you reach the zone, merge early rather than at the last moment, and increase your following distance. Avoid distractions — construction zones are exactly where a moment of inattention causes a crash.
Checking for Active Construction Before You Drive
MoDOT’s traveler information resources and most navigation apps show active construction zones and lane closures in real time — worth a quick check before a longer trip on unfamiliar routes.
Frequently Asked Questions
What if I break down inside a construction zone?
Get as far out of the active lane as the space allows, turn hazards on, and call for a tow right away — construction zones carry higher risk for a stopped vehicle.
Are construction zone speed limits strictly enforced?
Yes — fines are often higher in construction zones, and enforcement tends to be more consistent given the added safety risk.
How can I find out about construction before I drive?
