Veterans Memorial Tollway (Interstate 355)
Interstate 355 (I-355), commonly known as the Veterans Memorial Tollway, is a significant Interstate Highway and tollway located in the western and southwest suburbs of Chicago, Illinois, in the United States. It serves as a crucial transportation artery, facilitating movement and commerce in the northeastern part of Illinois.
Historical Background
The idea for I-355 emerged in response to burgeoning suburban development and increasing traffic congestion in Cook County and DuPage County. Initially, tollway officials designated the road as I-355. However, early in 1988, the Federal Highway Administration suggested the designation be changed to Interstate 455. Despite this recommendation, the I-355 designation prevailed.
The tollway officially opened on November 18, 1993, coinciding with the launch of the I-Pass, a system designed to streamline toll collection using transponders. The highway is maintained by the Illinois State Toll Highway Authority, which ensures its upkeep, addressing issues like pavement quality and expected traffic loads.
Route Description
I-355 spans approximately 32 miles, connecting the cities of Bolingbrook and Joliet. It intersects with major highways including Interstate 55 and Interstate 80, providing critical links for regional traffic flow. The tollway also crosses the Des Plaines River Valley Bridge, a major infrastructure achievement that carries it over the Des Plaines River, the Chicago Sanitary and Ship Canal, and several rail lines.
Construction and Infrastructure
In anticipation of heavy traffic and to avoid issues experienced on other roads, the Illinois State Toll Highway Authority decided to construct I-355 with durable materials. This included laying a 12-inch layer of concrete over an 8-inch sub-base, designed to extend the road's lifespan to 20 years. This decision underscores the importance of I-355 as a robust and reliable transportation route.
Economic and Social Impact
The presence of I-355 has had a profound impact on local communities such as Romeoville, stimulating economic growth and suburban expansion. It has significantly reduced travel times and improved access to various municipalities, making it a vital component of the region's infrastructure.
