Interstate 70: St. Louis, Missouri to Effingham, Illinois

Take an eastbound journey from the industrial heart of St. Louis to the open agricultural country of southern Illinois as we follow Interstate 70 for approximately 100 miles from St. Louis Street to Illinois Route 33 in Effingham. Along the way, we cross the Mississippi River on one of the region’s most recognizable modern bridges, thread through the complex highway network of the Metro East, and settle into a long rural drive past farmland, wooded creek bottoms, historic communities, and some of Illinois’ most important east-west transportation corridors.

We begin near St. Louis Street, where Interstate 70 carries us through the densely developed northern side of St. Louis. Warehouses, rail infrastructure, older industrial properties, closely spaced exits, and the city’s broad urban street grid surround the highway as we approach the Mississippi River. This is one of the busiest and most visually complex portions of the drive, with traffic moving between downtown St. Louis, North St. Louis, the riverfront, and several major interstate connections. Ahead, the towers and cables of the Stan Musial Veterans Memorial Bridge rise above the river, marking both our crossing into Illinois and one of the defining moments of the journey. The bridge carries Interstate 70 directly across the Mississippi River, providing a modern northern alternative to the older river crossings closer to downtown.

Once across the river, we enter East St. Louis and the Metro East transportation network. The landscape remains intensely urban and industrial, shaped by freight yards, elevated ramps, utility corridors, levees, warehouses, and the transportation infrastructure that has grown around the Mississippi River for generations. Interstate 70 works through a complicated series of connections with Interstate 55, Interstate 64, Illinois Route 3, and nearby approaches serving downtown St. Louis. This short portion of the trip illustrates the Metro East’s longstanding role as a gateway between the river city and the highways extending across Illinois. Traffic patterns can change quickly here, but the route soon begins turning away from the river and toward the eastern suburbs.

As we continue through St. Clair County, Interstate 70 passes the approaches to Collinsville, Fairmont City, Caseyville, and O’Fallon while intersecting Interstate 255 and other regional highways. Commercial districts, suburban development, distribution facilities, and residential areas line much of the corridor. The road is still unmistakably metropolitan, but the crowded industrial scenery near the river gradually becomes more spacious. Beyond the busiest suburban interchanges, development begins breaking into separated clusters, and broad areas of open ground appear between communities. We are leaving the continuous urban fabric of St. Louis behind and entering the transitional landscape between the Metro East and rural southern Illinois.

Near Troy, the character of the drive changes more decisively. The interstate straightens across Madison County, passing expanding suburban neighborhoods, roadside services, and open agricultural land. Troy serves as one of the final major suburban centers along this portion of Interstate 70, although development continues intermittently toward Highland. East of town, large cultivated fields begin dominating the view, interrupted by farmhouses, grain storage facilities, windbreaks, and narrow bands of woodland following streams and drainage channels. The highway crosses gently rolling terrain rather than perfectly flat prairie, producing long views across fields while occasionally dipping into wooded creek valleys.

Continuing east, we pass the Highland area and the Silver Lake region before entering Bond County. The density of interchanges decreases, traffic generally becomes less frantic, and the journey settles into the steady rhythm of a rural interstate drive. Greenville emerges as the principal community along this middle section of the route. Interstate 70 remains outside the traditional center of town, serving modern travel plazas, restaurants, lodging, and regional businesses while connecting Greenville with St. Louis and communities farther east. This is also where the new video begins overlapping the previously published Greenville-to-Effingham segment, carrying us over familiar pavement for the remainder of the journey.

Beyond Greenville, the highway moves through a landscape defined by agriculture and small communities. Near Mulberry Grove, fields stretch away from both sides of the roadway, with stands of hardwood trees marking property lines, creek bottoms, and older farmsteads. Freight traffic becomes a prominent part of the experience, reflecting Interstate 70’s importance as a national east-west corridor. The highway does not enter most of the communities it serves; instead, interchanges connect the mainline with local roads leading toward town centers, farms, schools, and businesses. This separation allows the interstate to maintain its broad, uninterrupted character while older U.S. Route 40 continues to link many of the communities more directly.

Approaching Vandalia, the landscape remains largely rural, but roadside services and local traffic increase around the city’s interchanges. Vandalia holds an important place in Illinois history. The community served as the state capital during the early decades of statehood, and the surviving Vandalia State House served as Illinois’ capitol from 1836 until 1839. Although Interstate 70 bypasses the historic center, its exits provide access to the statehouse, downtown Vandalia, and U.S. Route 40. The older highway follows the historic National Road corridor through the region, creating an interesting contrast between the slower community-oriented route and the modern interstate carrying us east.

East of Vandalia, Interstate 70 resumes its long passage through farmland, scattered woodland, and lightly populated countryside. We pass near Brownstown and St. Elmo before approaching Altamont, where local development becomes more noticeable around the highway. The countryside here reflects the working agricultural character of south-central Illinois: broad fields, grain elevators, barns, farm machinery, and small settlements connected by a grid of county roads. Changes in elevation remain subtle, but shallow valleys and tree-lined waterways keep the scenery from becoming completely uniform.

The final miles bring us toward Effingham, one of Illinois’ most important highway crossroads. Commercial development, hotels, restaurants, warehouses, and transportation-oriented businesses become increasingly common as we approach the city. Effingham’s regional identity is closely tied to the meeting of east-west Interstate 70 and north-south Interstate 57, an interchange that has made the community a major stopping point for travelers and freight traffic. Our drive concludes at Illinois Route 33, paired locally with Illinois Route 32, just west of the principal I-57 and I-70 junction. The Effingham visitor bureau describes the city in terms of this crossroads location, where the two interstates connect travelers with destinations across Illinois and the central United States.

From the tightly packed expressways and industrial riverfront of St. Louis to the broad fields surrounding Effingham, this 100-mile drive shows how quickly the Midwest can shift from metropolitan intensity to open country. Interstate 70 serves as the constant thread, carrying us across the Mississippi River, through the Metro East suburbs, past one of Illinois’ former capitals, and toward a modern crossroads built around movement. What begins amid bridges, railroads, and city traffic ends beneath an expansive Illinois sky, surrounded by farmland and highways stretching toward the horizon.
