In my recent use of I-72 between Champaign and Decatur and subsequently the use of US-51 from Decatur to Pana, I did notice that that district has started to put LED fixtures to good use.

Hopefully the email to consider it a couple years ago resonated well in IDOT brass or at least with the District leads.

Keep going Illinois! With your roads budgets separated now, every dollar saved here goes to better work in the future.

When I was at IDOT, around 2001 we spec'd LEDs for bridge navigation lights (the red and green clearance marker lights) on one of our projects, hoping to save on bulb changing costs. At the time they were fairly expensive, like $1,000 a unit. 20 years later, IDOT just opened up the IL 178 bridge in Utica (a project I was project manager for), and everything is LED, including the navigation lights, roadway lighting, and some decorative lights along a parallel pedestrian/bike trail.

Today LEDs are becoming the defacto standard elsewhere, including home lighting, and naturally the price came down as they began to be mass produced on today's scale. It was only a matter of time. Hopefully the suggestion was something they had considered, and looked at what ISTHA and the other states were doing.

FWIW: US-51 south of Decatur was pretty dead. Of course my line of sight was only a hour on a Saturday, not a typical M-F workday. Not so much a criticism but an observation, my issue with 4 lane freeways without limited access are the number of accidents at rural crossings. This trip was no exception as I was diverted off US-51 to old US-51 at Assumption because a truck t-boned what appeared to be a camper attempting to pull out.

Reminds me of my days on the original construction on I-55 while the US 66 expressway was still in place. The intersection of IL 47 and US 66 in Dwight was the first traffic light out of Chicago. Even with flashing "signal ahead" warning signs, it was the scene of more than a few fatal and severe injuries. There was at least one stoplight in most of the little towns along the route, and traffic zooming by at 70 mph in between them, as well as all the minor intersections where it was sometimes hard to get a break in oncoming traffic to get across and people would shoot through there, not a great recipe for traffic safety.

Yes, I do remember that light at Dwight.  There was another one at McLean (in front of the Dixie) and Atlanta during those US-66 to I-55 days. Can't tell you how many times I drove that route during the transition years.

Revive 755:
IDOT has placed some information online for redoing I-270:

* The IL 3 interchange gets further downgraded to a folded diamond with a design that resembles the IL 53 interchange with IL 62/Algonquin Road in Schaumburg (the merging of dual lefts down to a single lane works so well for EB IL 62 to SB IL 53  :banghead:)

* The signing plans in the Access Justification Report (larger file) show the secondary control cities of St. Charles and Effingham going away.


There are also plans to replace the I-57/IL 16 cloverleaf with a "raindrop diamond/dumbbell interchange.  https://idot.illinois.gov/projects/I-57-IL-16-Interchange-Reconstruction.html

I'd argue that alot of the congestion and crash issues are caused as a result of trucks just randomly cutting off motorists to pass another truck that was only going marginally slower (for example 59mph vs 58mph). I swear , I cannot have one totally smooth drive downstate and back without this happening.
