Interstate 74

 

Interstate 74 westbound (northbound) crossing the Iowa-Illinois Memorial Bridge across the Mississippi River. The westbound span was opened to traffic in 1935 with two-way traffic. The eastbound span was added by 1959.3 The suspension bridge carried U.S. 6 prior to the designation Interstate 74, which was added to the span once the freeway approaches were constructed in 1974.2 Photo taken 09/04/05.

Routing

Interstate 74, a diagonal (northwest to southeast) freeway, serves the Upper Midwest, Southern Great Lakes and Ohio River Valley area. Beginning in Iowa at the Interstate 80 interchange in Davenport of the Quad Cities, I-74 leads southward between Davenport and Bettendorf to cross the Mississippi River into Moline, Illinois. Turning east along side Interstate 280 at Quad City International Airport (MLI), I-74 meets Interstate 80 again before starting out on its own toward Galesburg. Once at Galesburg, Interstate 74 turns southeast toward Peoria, Bloomington-Normal, Champaign-Urbana and Danville in Illinois. Beyond the state line with Indiana, the freeway veers toward Indianapolis, before terminating at Cincinnati.

Several extant sections of Interstate 74 also exist in North Carolina, but they do not connect directly with the existing I-74 from the Quad Cities to Cincinnati.

Parallel U.S. Routes

Starting in the Quad Cities area, Interstate 74 follows U.S. 150 southeast to Danville, then follows U.S. 136 the rest of the way into Indianapolis. Southeast of Indianapolis, Interstate 74 at first follows U.S. 421, then U.S. 52 the final distance into Cincinnati.

Planned Improvements

Illinois and Iowa have joined for the I-74 Corridor Study in the Quad Cities area. Improvements underway included work to expand I-74 throughout the Quad Cities, interchange modifications, and a new Mississippi River bridge. Significant funds for the study were included in the SAFETEA-LU bill, signed into law in August 2005.

After years of delays, partially due to funding, construction on the new Mississippi River Bridge for Interstate 74 will kick off by fall 2017, with work running through 2020. Approach work includes the reconstruction of River Drive in Moline (completed in June 2015) and relocation of streets in Bettendorf (work between April 2015 and 2016). Total cost for the project is $1.1-billion.7

Previously (in the late 1990s), local officials had proposed moving Interstate 74 from its current alignment onto Interstate 280 (existing I-74 would have become Interstate 174); this request was denied in favor of researching methods to reconstruct Interstate 74 through the area.

High Priority Corridor

North Carolina's section of Interstate 74 is part of High Priority Corridor 5: I-73/74 North-South Corridor. Its designation in North Carolina is written into law. See Interstate 74 in North Carolina for more.

History

The original layout of the Quad Cities Interstate system planned for Interstates 74 and 80 to overlap from the current west end of I-74 through the Quad Cities into Illinois. I-80 as it is routed today from Davenport east to Le Claire and south to Colona, Illinois at Interstate 280 was to be designated Interstate 274. Alterations to this plan led to the current configuration before any construction began as the Interstate 74/80 overlap seemed redundant.1

In Iowa, Interstate 74 opened on in stages:.1

  1. August 30, 1968 - from Interstate 80 south to U.S. 6
  2. September 2, 1971 - U.S. 6 south to Kimberly Road
  3. November 26, 1974 - Kimberly Road south to the Mississippi River bridges

Within Illinois, Interstate 74 was completed initially through Peoria along the Illini Expressway and Murray Baker Bridge in December 1958. The cross-state route was finished in 1971 with the opening of I-74 between Bloomington and Mahomet.4,6

Through Peoria and East Peoria, the Upgrade 74 project between October 2002 and November 2006 rebuilt the freeway to modern standards. The $490-million project expanded I-74 to six and eight lanes, improved all Peoria interchanges, and rebuilt the approaches to the Murray Baker Bridge.5

Future Aspirations

Long range plans called for Interstate 74 to continue east and south of Cincinnati through West Virginia and Virginia into North Carolina and South Carolina, with the freeway ending in Myrtle Beach. However, only North Carolina has shown interest or made progress with building I-74. Ohio and West Virginia are unlikely to ever build their proposed portions of the route.

To make the connection between Cincinnati and Huntington, West Virginia, Interstate 74 was proposed to pass through either Ohio or Kentucky. A feasibility study of routing Northern Kentucky Outer Loop Interstate 74 http://transportation.ky.gov/planning/projects/projects/I-74/I-74.shtm in Kentucky was completed in March 2003, and it revealed that constructing an east-west bypass around Cincinnati to the south via Kentucky might be needed someday, but it was not necessary at the time. Another study at the time considered routing Interstate 74 along the AA Highway rather than Ohio 32.

In West Virginia, Interstate 74 was programmed to follow proposed Interstate 73 along U.S. 52; the two routes would split before entering Virginia, with Interstate 74 merging with Interstate 77 south into North Carolina.

Interstate 74 shields were first erected along a stretch of U.S. 220 freeway south of Asheboro, North Carolina and in 2000 along a stretch between the Virginia State Line and Mt. Airy, North Carolina. See Interstate 74 in North Carolina and High Priority Corridor 5 for more information and photos.

In South Carolina, a failed state resolution previously attempted to designate the Carolina Bays Parkway as part of Interstate 74, the Veterans Highway/Conway Bypass as part of Interstate 73, and the North Myrtle Beach Connector from Main Street to the parkway as part of a new route called Interstate 174.

The route of I-74 now is proposed to hook southwest from Wilmington, North Carolina to reach the Grand Strand via the Carolina Bays Parkway. I-73 may be built as a toll road but funding has been slow to garner. The North Myrtle Beach Connector was completed as an at-grade expressway and opened in September 2009.

Interstate 74 through Peoria was recently reconstructed to modern standards between 2002 and fall 2007. The $500 million work affected 11 miles of roads. Photo taken 05/27/08.
Quad Cities - 1972.
Construction of Interstate 74 northward from I-280 to the Iowa-Illinois Memorial Bridge replaced the route of U.S. 6 & 150 along 19th-27th Streets north to Downtown Moline. U.S. 6 was later shifted to the freeway northward to Kimberly Road while U.S. 150 was truncated southward from Moline to its intersection with U.S. 6 east of Quad City International Airport (MLI) in 1977.
