Highway system
Illinois State Highway System

The Tri-State Tollway is a U.S. toll road maintained by the Illinois State Toll Highway Authority (ISTHA) in northeastern Illinois which is considered one of the most heavily traveled highways in the country (according to the IBTTA, the tollway is the nation's 4th busiest toll road[2]). It is actually a combination of three different Interstates:

The segment containing Interstate 294 is 53 miles (85 km) long; in total, the Tri-State Tollway is actually about 78 miles (126 km) long. Only the Ronald Reagan Memorial Tollway is longer. Despite its name, the Tri-State Tollway does not enter either Indiana or Wisconsin. On the Indiana side, the Tri-State Tollway ends three miles (5 km) away from the Indiana border and continues as the Kingery Expressway; however both the Kingery and the Indiana portion, which was later named the Borman Expressway, were known as the Tri-State Highway before the Tollway was completed. On the Wisconsin side, the toll road ends just before the border at U.S. Route 41 and Russell Road, although ISTHA maintenance continues to the state line.[3][4]

Features[edit]

Northbound Interstate 294 in Alsip, one-half mile south of 127th Street.
  • Oases—these oases are a part of the entire tollway system, but the most are on the Tri-State Tollway. They provide food and gas without having to exit the tollway proper. They are built over the road.
  • Pay-as-you-go tolling—like all Illinois tollways, rather than getting an entry ticket and paying upon exiting the tollway, drivers pay a flat toll at toll barriers along the main line (every 10 miles (16 km) south of O'Hare Airport). There are also automated toll collection lanes at some exits and entrances.
  • Open road tolling—open road tolling allows the automatic collection of tolls via an I-Pass (compatible with E-ZPass), without the need to slow down or stop at a toll booth.
  • Thornton Quarry—about 0.75 miles (1.21 km) of the highway crosses a quarry being converted into a large lake for overflow storm water. Currently, the road's elevation over the floor of the quarry is up to 100 feet (30 m) deep on both sides of the highway, making for a unique view.
  • No direct interchange with Interstate 57—despite the fact that these two highways cross paths, there has always been room for an interchange to be built, and one is currently being planned by the Illinois Department of Transportation, ISTHA, and others.[5] I-57 and I-355 are the only Chicago area expressways that cannot be directly accessed from the Tri-State Tollway.

Lingo[edit]

The Tri-State Tollway near Illinois Route 176 in Libertyville

Portions of the Tri-State Tollway are referred to in somewhat archaic language during traffic reports and casual conversation. The following are the most common, from south to north:

  • Thornton Quarry—on I-80/294 just east of Halsted Street, the bridge over the aforementioned Thornton Quarry.
  • Mile-Long Bridge—on I-294 between I-55 and La Grange Road, the bridge over the Chicago Sanitary and Ship Canal, the Des Plaines River, a large portion of the UPS transmodal facility, a few rail lines, and some Commonwealth Edison power lines.
  • Grand Avenue Curve—the curve immediately south of the Bensenville Bridge (see below). This portion of the tollway functions as a long S-curve, causing delays due to limited visibility beyond both curves.
  • Bensenville Bridge—on I-294 just south of O'Hare, the bridge over the Metra Milwaukee District West line and Mannheim Road (US 12/US 45).

History[edit]

Tri-State Tollway in Glenview following late 2000s widening/rebuild, two miles south of Willow Road.

The Tri-State Tollway was built in the mid- to late 1950s as a bypass of Chicago, as the Indiana Toll Road-Chicago Skyway (opened in 1956) ran towards downtown. The first section opened August 28, 1958, running from Wisconsin south to and east along the Edens Spur. The rest of the road, from the Edens Spur south to the Calumet Expressway and Kingery Expressway, opened December 23 of the same year. It was at first marked as U.S. Highway 41 Toll, which continued east on the Kingery Expressway (now I-80/I-94) to Calumet Avenue (US 41) in Hammond, Indiana, and ended at the north end of the Tollway, where it merges with US 41. It was also marked as U.S. Highway 30 Toll between its south end (the Calumet Expressway was U.S. Highway 30 Alternate) and the East–West Tollway. In 1959 the Tollway was designated as parts of I-94 and I-294, and the short concurrency with I-80 was assigned.

In 1998, the authority removed the entire multilane Deerfield Toll Plaza on the Tri-State, then considered one of the worst snags on the tollway system. To make up for the lost tolls, the Tollway Authority built the Huehl Road Toll Plaza on the Edens Spur to charge traffic that followed Interstate 94 into Chicago. In addition, tolls at the Waukegan Toll Plaza were increased, and additional toll plazas built on exits south of Deerfield at Lake-Cook Road, Willow Road and Golf Road (Illinois Route 58). Toll collection facilities were also added to entrance ramps to the northbound Tri-State at those points.

Numerous projects to rebuild and widen the entire Tri-State Tollway were completed by early 2010.[6]

As of December 30, 2009, Clearview Font signage was installed on the Tollway system, and the mileposts of the I-94 portion of the Tri-State Tollway and Edens Spur no longer use the original milepost signage from IL-394 and I-80. Milepost signs north of Lake-Cook Road now use I-94's mileage from south of the Wisconsin state line. Example: I-294 going north has milepost numbers going up to mile 53. I-294 mile 53 becomes I-94 mile 25 going north with the milepost numbers going down. Milepost numbers are now visible every 1/4 mile, as opposed to the previous signage at 1/2 mile intervals.[7]

Edens Spur[edit]

Edens Spur
Location: Northbrook
Length: 5 mi (8 km)
Existed: mid-1950s–present

The Edens Spur is a five-mile (8.0 km) cutover from the Tri-State Tollway to the Edens Expressway. It connects the Interstate 94 portions of the tollway and the Edens Expressway. It is technically a toll road. Northbound traffic on the Edens Expressway has the option of cutting over to the northbound Tri-State Tollway, or remaining on U.S. Highway 41 (Skokie Highway). Southbound traffic on the Tri-State Tollway has the option of cutting over to the southbound Edens Expressway, or remaining on the Tri-State Tollway on the loop Interstate 294. There are no other ways to enter the Edens Spur at the ends. There is one exit eastbound on the Edens Spur at Illinois Route 43 (Waukegan Road). There is also an entrance ramp to the Edens Spur westbound at that point. The spur has one toll barrier, as it is still part of the Illinois State Toll Highway Authority system. This toll plaza has been upgraded and now has I-Pass open tolling lanes, which have eliminated most congestion at this toll.
