The first phase of what developers say will be the largest-capacity truck stop in the United States is now open in the Chicago area.

The 30-acre site is off Interstate 90, just west of the Fox River in West Dundee. It opens at the end of the month.

Finding a spot to park can be quite a challenge for many truck drivers. In Illinois, the American Trucking Association says there is one parking spot for every 11 trucks out on the road, and truckers say they frequently waste an hour a day searching for a spot to park.

The new truck stop site is located on the former Elgin landfill, which closed in the 1970s. The facility will eventually have 1,000 semi-truck parking spaces, which will add nearly 10% more spaces to the statewide total.

Drivers will have to book spots in the yard in advance. Company officials say the location of the yard, along the booming I-90 corridor from O’Hare Airport to Rockford, is key. New industrial development in the region is growing quickly, with much of that supporting e-commerce and the expectation of speedy delivery of products ordered online.

The parking is expected to open very soon, but they expect to add a maintenance facility, convenience store and office space by the spring.
