Grand Rapids Breakdown Help: What to Do When Your Car Quits on the US 131 S-Curve
If your car dies on the US 131 S-Curve in downtown Grand Rapids, call 911 first if you're stuck in a live lane or anyone is hurt. Then give your direction, northbound or southbound, and the last street you passed: 28th Street, Wealthy Street or Pearl Street. Say whether you're north or south of the Grand River. That one sentence lets a driver find you on the busiest stretch of road in West Michigan.
Where exactly is the S-Curve?
The S-Curve is the bent piece of US 131 right through downtown. MDOT says it runs from Wealthy Street to Pearl Street. Over that span, the freeway rides on bridges above the Grand River and the local streets below.
Heading north, the road swings hard west at Wealthy Street. It crosses the river, then bends back north. That's the "S" you feel in the wheel.
The bridges were rebuilt in 2000. MDOT expects most of them to last at least another 50 years. So the curve isn't going anywhere. Neither are the backups.
Why is this the stretch where breakdowns hurt most?
MDOT's own study looked at US 131 from 28th Street up to Wealthy Street. It found that piece carries the highest volumes of any road in Michigan outside Metro Detroit. MDOT also says it has frequent congestion, delays and incidents. So a stall here, at rush hour, backs things up fast. A clear location gets help to you sooner and gets you out of that traffic.
How do I describe my spot on the S-Curve?
Saying "on 131 downtown" isn't enough. The curve is mostly bridges and ramps, close together. Here is what to say, in this order:
- The road: US 131.
- Your direction: northbound or southbound. Read it off the last green sign if you're unsure.
- The last street you passed: 28th Street, Wealthy Street or Pearl Street.
- River side: north or south of the Grand River, or on the bridge over it.
- Lane or shoulder: right shoulder, left shoulder, or in a lane.
A street address in Grand Rapids uses a quadrant, like NE or SW. That helps on city streets, where Fulton Street and Division Avenue split the quadrants. On the freeway, skip the quadrant. The street names and the river matter more. If your phone can share your location, do that too.
What's different on the S-Curve this fall?
MDOT is replacing the lights on US 131 between Wealthy and Pearl, both directions. Work started May 26, 2026. MDOT's estimated end date is mid-November 2026.
Until then, MDOT says lane closures, ramp closures and traffic shifts can happen at any point in the project. That changes a breakdown in two ways:
- The ramp you planned to limp off at may be closed. Don't swerve for it. Stop where you can.
- Lanes may be shifted from where you're used to them. Tell your driver which lane or shoulder you're actually on.
Before you drive downtown, check MDOT's Mi Drive map. It shows live cameras, speeds, construction and crashes. MDOT also lists a bridge job on Martin Luther King Jr. Street, which is Franklin Street, just east of US 131 in 2026 and 2027.
My car died in a lane on the curve. What now?
Your engine cuts out on the bridge, and cars are flying past on both sides. Here's the order:
- Hazard lights on, right away.
- If the car still rolls, steer to the shoulder.
- If it stops in a lane, stay in your seat with your belt on.
- Call 911. A car stuck in a live freeway lane is a danger to everyone.
- Don't get out to look under the hood. Don't walk on the bridge.
- Once police or the road is safe, call for a tow.
If you make it to a downtown street instead, and nobody is hurt, the Grand Rapids Police non-emergency line is 616-456-3400.
Do I have to move my car after a fender bender on US 131?
Often, yes. Michigan's law, MCL 257.618a, says what to do after a crash when nobody is seriously hurt. If the car can be driven safely, a licensed driver in the car must move it out of the main lanes. The shoulder, the emergency lane, the median or off the road all count.
- This only applies if moving it can be done safely.
- The car must run and drive normally under its own power.
- Not moving it when you should is a civil infraction.
- Moving it doesn't make you at fault for the crash.
If the car is blocking the road, police can have it removed without your OK. So if your car can roll, get it out of the S-Curve's lanes. If anyone is seriously hurt, leave the car where it is and call 911.
Will MDOT's free patrol help me?
Maybe, but don't count on it. MDOT runs a Safety Service Patrol in Kent County. It costs you nothing. MDOT says the patrol helps stranded drivers, clears debris and marks abandoned cars.
| Patrol detail | What MDOT says |
|---|---|
| US 131 | 100th Street to 10 Mile Road |
| I-96 | Fruit Ridge Avenue to M-50 |
| I-196 | 44th Street to I-96 |
| Days and hours | Monday to Friday, 6 a.m. to 7 p.m. |
| Operators | Up to two at a time |
The catch is big. MDOT says you can't request the patrol, and there's no phone number to call. They find you, or they don't. At night, on a weekend, or anywhere off those freeways, nobody from that patrol is coming.
How long can I leave my car on US 131?
Not long. Under MCL 257.252a, a car with a valid plate counts as abandoned after 18 hours on a state trunk line highway. On other public property, the limit is 48 hours. Police may put a notice on the car and then have it towed.
If you leave the car, call for a tow before that clock runs out. Sentinel doesn't do impounds. If police already took your car, our Grand Rapids impound guide explains how to get it back.
Do drivers have to move over for me?
Michigan's move-over law, MCL 257.653a, protects stopped emergency vehicles with flashing lights. Drivers must slow to at least 10 mph under the limit. With two or more lanes their way, they must also move over a lane, or two car widths, when they can. That law is written for emergency vehicles, not for your car. So don't trust passing drivers to give you room. Stay buckled in with the hazards on.
Do I need a tow, or something smaller?
Lots of Grand Rapids breakdowns don't need a hookup. Match the help to the problem.
- It clicks and won't start in a downtown parking lot. Try a jump start first.
- A flat on the shoulder past Wealthy. If you have a good spare, a flat tire change puts it on.
- Keys locked inside after you parked downtown. A car lockout visit gets you back in.
- It won't drive, or it's smoking or leaking. That's a tow. Name a shop before you call.
How does Sentinel fit in?
Sentinel Towing is a towing and roadside network. A vetted local partner tow company does the job. We text you a locked price before anyone is sent. You get your driver's name, photo and truck by text, and you can track your truck on a map. We check in by text until help arrives. That's our Stay-With-You Promise. Sentinel is not an emergency service, so call 911 first when anyone is hurt.
The Grand Rapids towing page covers I-96, I-196, M-6 and lake-effect snow. For other cities, see Michigan towing.

Grand Rapids S-Curve Questions
Where does the S-Curve start and end?
MDOT puts it between Wealthy Street and Pearl Street on US 131. It crosses the Grand River on bridges. If you're between those two streets downtown, you're on it.
Can I call MDOT's Safety Service Patrol?
No. MDOT says the patrol isn't on demand and has no phone number. It runs weekdays on set Kent County freeways. If they don't find you, call for roadside help yourself.
Is the S-Curve still under construction?
MDOT's lighting job there runs to an estimated mid-November 2026. Lane closures, ramp closures and traffic shifts can happen until then. Check Mi Drive before you go.
My car is dead on the shoulder. Can I leave it overnight?
Be careful. Michigan law treats a plated car as abandoned after 18 hours on a state trunk line highway. Police may tag it and have it towed. Arrange a tow before then.
Rules change, so check the official source before you rely on it. Sources: MDOT US-131 PEL study FAQ, MDOT S-curve lighting project, MDOT WMTOC and Safety Service Patrol, MCL 257.618a, MCL 257.252a, MCL 257.653a, Grand Rapids Police contacts, Mi Drive.
