US-20 and US-218: four lanes and no rest areas

US-20 is a four-lane divided highway for its whole length in Iowa, and east of Waterloo it runs as a freeway. After I-380 ends, US-218 runs through downtown Waterloo to Cedar Falls. It then heads northwest as a four-lane highway through Waverly toward the Floyd County line. Every state rest area in Iowa is on an interstate, so neither road has one. A stop on either usually means the shoulder or the next exit.

On the shoulder, keep the hazards on and stay belted in. A crash, an injury or a car in a live lane is for 911. For everything else, call (319) 271-6565 with the road, the last exit and your direction. We quote the job and the timing on that call, whichever of the two roads you are on.

Questions

Is there a rest area anywhere on US-20 across the Cedar Valley?

No. Iowa builds its state rest areas only along interstates, so US-20 through the Cedar Valley has none. The 24-hour stop on it is Love's Travel Stop #702 at the Sergeant Road exit, 227, in Waterloo. If your car can reach that lot, a jump start there costs from $79.

I broke down on US-218 near the Janesville exit. What do I tell you?

Give the last US-218 exit you passed near Janesville, such as 192 for County C57, 195 for Janesville or 198 for Waverly. Then say which way you were headed and whether the car is on the shoulder. With that, we can price the tow, from $117, on the call.

Which US-20 exit is the University of Northern Iowa?

Exit 224, Iowa 58 south (Hudson Road), is the US-20 exit signed for UNI and the UNI-Dome in Cedar Falls. If you stall near it, tell us the exit and your direction of travel. A jump start near the UNI-Dome exit costs from $79.
