Construction is virtually present on some part of I-465 all throughout the year. The State of Indiana sets active construction zone speed limits of 45MPH on Interstate highways, both urban and rural. Although traffic is rarely enforced strictly on I-465 in general, enforcement is very strict in construction zones, namely during active periods, indicated by flashing lights on the 45 speed limit signs (or all the time when there are no lights at all on the sign). Please note that there is almost ALWAYS a cop sitting a quarter mile or so from each end of each active construction zone. I have seen people pulled over for 50-55, which is especially nasty when the area between Pendleton Pike and I-70 East has construction, namely due to the reasonably tall and steep hill/valley at Shadeland Ave.
