Depends on how far apart the stoplights are. 😉 You can go pretty far on a frontage road without stopping in some places. Especially noticeable when the real highway traffic is at a standstill.

Frontage roads create eyesores. Just strip malls, gas stations, and motels for miles. And if you’re terribly unlucky, you live in an apartment or subdivision built right next to the highway.

I remember the first time I drove through a state that didn’t use frontage roads on a multi lane highway, and realized how much nicer it was to exit into an actual neighborhood.
