Tulsa Roadside Guide: How to Get Help on the Inner Dispersal Loop

If your car quits on Tulsa's Inner Dispersal Loop, turn on your hazards and tell the dispatcher which leg you're on: north, west, south or east. Add your direction and the last street ramp you passed, like 7th Street or 11th Street. The IDL is a ring of freeways around downtown, and each leg carries more than one highway number. Naming the leg gets your driver to the right side of the right road.

What is the IDL, and why does it confuse callers?

The Inner Dispersal Loop is the box of freeways that wraps around downtown Tulsa. Locals just call it the IDL. It ties into almost every big highway in the city. In 2009, ODOT put it at about 62,000 vehicles a day.

Here's the catch. Most of the loop has two, three or even four route numbers stacked on it. A driver on the west leg may see I-244, US-64 and SH-51 on the same sign. Someone calling from there could say any one of those. Your driver might picture a different road.

So skip the route numbers at first. Say the leg. ODOT itself talks about the loop this way, as the north, west, south and east legs.

Which highways make up each leg of the IDL?

Leg	Highway numbers on the signs	Good landmarks to name
North leg	I-244 and US-412	The ramps at Cincinnati and Detroit
West leg	I-244, US-64 and SH-51	Near the Arkansas River, on the downtown side
South leg	US-75, US-64 and SH-51	The ramps at 11th Street or 13th Street
East leg	US-75, called the Cherokee Expressway	The ramp at 7th Street

The south and east legs are also I-444 on paper. You won't see that number on the signs, though. They're signed as US-75, plus US-64 and SH-51 on the south side. If you say "I-444," a driver from out of town may not know the road. Say "the south leg of the IDL" instead.

What happens at the four corners of the loop?

The corners are the hardest spots to describe. Each one is a big split where highways join or leave the loop.

• Southwest corner: this is I-244 exit 4B, right by the Arkansas River. US-75 peels off to the south leg here. US-64 and SH-51 join I-244 for the west leg.
• Northwest corner: US-64 and SH-51 leave with US-412 heading west as the Keystone Expressway. The L.L. Tisdale Parkway runs north from here.
• Northeast corner: I-244 meets the east leg. US-75 keeps going north toward Bartlesville. I-244 and US-412 head east, out past Admiral Place.
• Southeast corner: US-64 and SH-51 split off east as the Broken Arrow Expressway, the BA. US-75 turns north onto the east leg.

If you stall on a ramp between two highways, say so. "I'm on the ramp from the BA to the east leg" is far clearer than "I'm on 75."

What should I tell the dispatcher, word for word?

Keep it short. Read the signs around you if you can. Give these five things in this order.

1. The leg: "I'm on the north leg of the IDL."
2. Your direction: eastbound, westbound, northbound or southbound.
3. The last street ramp you passed, or the next one you can see.
4. Which lane or shoulder you're in: right shoulder, left shoulder, or a ramp.
5. What the car did: "It died and won't crank" or "the tire blew."

Then share your phone's location pin when the text comes in. On a ring road, the pin plus the leg is the best combo. The pin shows the spot. The leg shows which way you're facing.

Not on the loop? The same idea works on the BA, the Cherokee Expressway north of downtown, or I-244 east of the loop, which some maps call the Crosstown Expressway. Give the road, the direction and the last cross street.

What kind of help can come to me on the loop?

Most loop breakdowns fall into a few kinds. Here's how each one plays out.

• The car died and won't crank: a jump start may get you moving. If it dies again, plan on a tow.
• A tire blew on the shoulder: your driver can put your spare on with a flat tire change. The spare has to hold air. No spare means a tow to a tire shop.
• You parked downtown and locked the keys in: a car lockout visit opens the door. It can't cut a new key.
• The car won't run at all: it gets towed to your shop or your home.

Your price depends on the job, your vehicle, where the car sits and how far a tow goes. You get it by text before anyone is sent. That number is the most you pay. If the job changes once your driver sees the car, you get a new price by text first, and you decide.

What does Oklahoma law expect of me if I stall on the IDL?

A few state rules shape what you do right after the car quits.

Clear the lane if the car still moves

Under 47 O.S. 11-1001, if your car blocks traffic, you're expected to make every reasonable effort to get it out of the way. That rule doesn't cover crashes where someone is hurt or killed. So if it still rolls, coast to the shoulder or down the next ramp. If it won't move, stay belted in with your hazards on.

Don't walk the loop

Oklahoma law, 47 O.S. 11-313, lets road officials post signs that ban people on foot from controlled-access roads. Walking a freeway shoulder to find a gas station is a real danger. Stay put and call.

Passing drivers must move over

The Bernardo-Mills Law, 47 O.S. 11-314, says drivers must change lanes away from a stopped car with flashing lights, or a wrecker with a flashing amber light. If they can't move over safely, they have to slow down. Not everyone does, so stay inside the car unless it's on fire or you're told to get out.

If you're stuck in a live lane, or anyone is hurt, call 911 first. Sentinel is not an emergency service.

Who actually comes to help?

Sentinel Towing is a towing and roadside network, not a tow company. A vetted local partner tow company does the work. We lock your price by text first. Then we text you your driver's name, photo and truck, and we check on you by text until help arrives. That's our Stay-With-You Promise. You can also follow the truck on a map as it works its way around the loop toward you.

How can I check the loop before I drive it?

ODOT keeps a road conditions line at 844-465-4997, also written as 844-4OK-HWYS. It's updated during bad weather and emergencies. ODOT's Drive Oklahoma tools show traffic maps, road conditions and live traffic cameras. A quick look before you head downtown can steer you around a closed ramp.

Weather matters too. NOAA's normals for Tulsa show about 8 days a year when the high stays at or below freezing. On those days, a curved ramp can turn slick fast. Summer brings about 66 days a year at 90°F or hotter, which is hard on old batteries and worn tires. May is usually the wettest month, so watch for standing water in low spots after a storm.
