What Is the Silver Lake Rest Area?
The Silver Lake Rest Area is an official highway rest facility located along Interstate 70 near Highland, Illinois, approximately 27 miles east of St. Louis, Missouri. It is maintained by the Illinois Department of Transportation (IDOT), which oversees a statewide network of 30 rest areas and 11 welcome centers on highways throughout Illinois.
What makes Silver Lake unique among Illinois rest stops is that it actually operates as two separate facilities — one for each direction of travel on I-70:
- Silver Lake Welcome Center — serving I-70 Eastbound travelers
- Silver Lake Rest Area — serving I-70 Westbound travelers
Both facilities sit at approximately Mile Marker 27 on I-70, making them easy to spot from the highway. The eastbound facility carries the designation “Welcome Center,” meaning it offers a slightly elevated set of services including travel information and visitor assistance.

Tips for Your Stop
Check your fuel before you stop. Silver Lake has no gas station. If your tank is getting low, plan to fill up in Highland or one of the exits before you reach Mile Marker 27.
Use it as your last comfort stop before Indiana. If you’re heading east on I-70, Silver Lake’s Welcome Center is strategically your last proper rest stop before a long gap. Don’t skip it.
Bring your own snacks. Vending machines are available, but selection is limited. Having your own food and drinks will make the stop more enjoyable.
Leash your pets. The rest area is pet-friendly, but all pets must remain leashed at all times on the grounds.
Plan for the 3-hour limit. If you need a longer rest, consider pulling into a nearby truck stop or motel in the Highland area rather than risking a parking enforcement issue.
Visit during daylight if possible. The grounds are particularly scenic and peaceful during daylight hours, with shaded picnic shelters and a pleasant natural setting that gives the area its “Silver Lake” character.
