Why did you decide to switch it so I-155
traffic will travel over I-74 traffic?
By removing the bridges over the abandoned railroad on
I-74 just east of the interchange we are able to keep
I-74 at a flatter grade through the interchange and
switch I-155 over I-74. This configuration allows for
greater safety and ease of driving for motorists using
the ramps at the interchange by eliminating rapid
acceleration or deceleration upon exiting or entering
What are the benefits of this project?
Removal and replacement of the deteriorated structures
on I-74 combined with reconstruction of the roadway and
ramps to current policy standards provides for a safer
system that accommodates the large number of motorists
using the interchange on a daily basis. This
configuration, which includes the addition of an extra
lane both eastbound and westbound on I-74, will reduce
congestion and delays and better accommodate both truck
and vehicle traffic.
How many lanes will be open on I-74
Two traffic lanes both eastbound and westbound will be
provided on I-74 throughout the construction timeline.
However, periodic lane closures or lane reductions at
isolated locations to set up traffic staging or perform
spot construction work may occur.
Why are we doing this improvement?
This section of I-74 contains a total of eight
structures that were all constructed in the early
1960’s. The pavement was also completed at that time.
The system has performed well over the years, but is
approaching the end of its service life. We are bringing
this interchange and section of I-74 up to current
design standards for improved safety and efficiency for
How can I help?
Every effort has been made to reduce your delay and
provide for safety for not only yourself, but also to
the construction workers. Delays will still occur
though, and you should plan extra time for your trips
through the work zone. Carpool if possible, adjust your
trips to off-peak traffic flow times, or avoid the work
zone altogether. This project will have a reduced speed
limit through the work zone. As with all work zones,
slow down and use extreme caution. Put down your cell
phone and eliminate distractions while driving through
the work zone.
