Draft Purpose and Need Based on six recent studies:  Efficient Use of Highway Capacity, November 2010  I-70 Reversible Lane Phase 1 Feasibility Study , August 2010  I-70 Hard Shoulder Running Report , July 2011  I-70 Mountain Corridor Mobility and Operational Assessment , August 2011  I-70 Reversible Lane Phase II Feasibility Study , March 2012  I-70 Peak Period Shoulder Lane Feasibility Study , March 2013

Draft Purpose The purpose of the PPSL project is to:  Provide short-term eastbound operational improvements.  Relieve traffic congestion during peak periods.  Be implemented within a short time frame.  Avoid substantial construction outside of the existing I-70 highway footprint.  Be implemented in advance of longer-term major improvements to the I-70 Mountain Corridor.

Draft Need Statement TRAVEL TIME RELIABILITY  Severely compromised  Affects tourism  Affects economic development  Affects transportation-dependent commerce

Draft Purpose and Need MOTORISTS DIVERT TO ALTERNATE ROUTES  Causes congestion on the frontage road.  Causes reduced safety on the frontage road.  Frontage road provides access to numerous adjacent properties and has a lower speed.  Frontage road is not suitable as an alternate route for I-70 traffic.

Draft Need Statement CONGESTION-RELATED CRASHES  Far more crashes occur in the eastbound direction than in the westbound direction.  For rear-end crashes, 69% of total crashes for eastbound and westbound occurred in the eastbound direction.  For sideswipe crashes, 70% of total crashes for eastbound and westbound occurred in the eastbound direction.

Draft Need Statement EMERGENCY SERVICE PROVIDERS ARE DELAYED AND COMPROMISED.  Emergency vehicles have no other way to get to an incident on I-70 than to try to maneuver around traffic that is stopped because of congestion.  The resulting delay in effective incident management compromises safety, substantially inconveniences other travelers, and results in economic and environmental impacts.
