Traffic Bottlenecks

Combating Bottlenecks


Multi-headed solutions at one interchange will save from having to tear it down and rebuild it completely.

Background: Some short term fixes are planned until a long-term project can be effected.

Bottleneck Project: I-465 / I-69 Interchange. The problem: only two lanes of SB I-69 head to both directions of I-465 (south and west), compounded by the fact that there are only three lanes on WB I-465. This area experiences recurring congestion. The solution is multi-headed. 1) for three interchanges on I-69 investigate the signal timings on the ramps. 2) for the SR 37 corridor north of I-69 investigate the signal timing and roadway geometrics of three upstream intersections. 3) Add lanes to two ramps. 4) Add a lane in the median on I-69. 5) Remove the SB Binford Boulevard-to-EB 75th street LT movement and replace with a boulevard LT lane system. 6) future consideration to add an auxiliary lanes. A long-term fix is about to go to RFP. The long term fix will add lanes to the mainlines of both I-69 and I-465. Also, future plans include a fully developed Advanced Traffic Management System (ATMS) that will allow for ramp metering if necessary and desirable.
