WHAT IS THE PURPOSE AND NEED? Need is a tangible fact based problem ; i e a Need is a tangible fact based problem ; i.e. a transportation deficiency Purpose is an overarching statement of why you are pursuing the project; objectives that will be met to pursuing the project; objectives that will be met to address the transportation deficiency Purpose and Need Report Need: Address Operational Deficiencies Technical Analysis Problem Statement Stakeholder Input Traffic signal delay High volume turn Signals (traffic/ movements pedestrian) Unacceptable level of service on Weber Road service on Weber Road Inadequate lane Inadequate lane Street lighting/ Street lighting/ and I ‐ 55 ramps marking pedestrian lighting Merging issues Roadways compatible to existing businesses Poor signage Roadways compatible Traffic signal delay to existing commuting patterns 3

Purpose and Need Report Need: Improve Capacity Technical Analysis Problem Statement Stakeholder Input Projected increase in High volume of trucks Industrial centers and traffic volumes commercial areas No alternate north ‐ Substandard geometrics Substandard geometrics south routes south routes Commuter corridor Commuter corridor (travel lanes, Inadequate access to I ‐ Congestion and delay intersections) 55 Congestion Purpose and Need Report Need: Improve Safety Technical Analysis Problem Statement Stakeholder Input High number of crashes Motorist delay Traffic Safety Multi ‐ modal conflicts Prevents efficient access Congestion and delay High number of rear ‐ Congestion Handicap accessibility end and sideswipe Lack of pedestrian, Sidewalks and collisions ADA, and bike facilities pedestrian crossings Crashes data consistent Improve pedestrian Bike lanes/recreation with congestion access and bike path facilities No crosswalks or continuity continuous bike paths 4

Project Purpose The purpose of the proposed action is to address congestion and mobility problems in the Weber Road corridor identified in the study area, improve community connectivity, and improve access for commercial and residential users of I ‐ 55 and Weber Road Road. Project Purpose The purpose of the proposed action is to address operational , capacity and safety deficiencies of the interchange capacity , and safety deficiencies of the interchange at Interstate 55 and Weber Road in Will County, Illinois . 5

Project Purpose The purpose of the proposed action is to address operational, capacity, and safety deficiencies of the interchange at Interstate 55 and Weber Road in Will County, Illinois. Purpose and Need Report QUESTIONS 6
