Problem Statements
►The north-south arterial street network in Des Moines is not continuous Merle Hay Road and Beaver Avenue end north of I-235
2nd Ave., 6th Ave., Lower Beaver Road end south of I-235
MLK, Jr. Pkwy ends at Euclid Avenue
►Consequences of the problem include: Arterial/commuter traffic routing on local streets
►Peak hour traffic congestion
►Safety concerns for neighborhoods
A four-mile gap between I-35/80 interchanges►Increased travel time to I-35/80, notably from Des Moines
neighborhoods
►Reduced access to CBD from I-35/80

Project Description and Purpose
►Proposed Action: A continuous north-south transportation corridor through the Des Moines metro area (between Interstate-235 and IA 415/Oralabor Road)
►Project Purpose: Safely and efficiently accommodate existing and projected local and regional traffic between I-235 and IA 415.
6
Project Need
►System Linkage (continuous north-south arterial)
►Interstate Access (additional I-35/80 interchange)
Access for Projected Growth Areas Reduce Out-of-Distance Travel
►Safety (reduce crashes through traffic reduction or road improvements)
►Increase Road Capacity I-235 Capacity (2020 Analysis/Limited Build
Alternative/Inverted “Y”)
Improve M.L. King, Jr. Parkway Capacity►No Build Alternative increases traffic congestion
7
Project Status
►Alternatives Screening
Initial Screening to determine if alternatives meet Purpose and Need of project (in progress)
Anticipated results to public Fall 2009
The project purpose must address the following needs:
►Need for continuous north-south arterial providing service to CBD and airport
►Need for improved I-35/80 interchange spacing
►Need for additional road capacity between I-235 and IA 415

North End Concepts*
►IA 415 – I-35/80: Widen or build four-lane arterial street
►Add I-35/80 Interchange
►I-35/80 to Euclid Avenue:
Widen or build four-lane arterial street
Includes a Des Moines River bridge
* Based upon initial study; subject to change
9
Factors to be Considered within EIS: North End
►Des Moines “Complete Streets” policy
►Provide a new crossing of the Des Moines River
►Design road to be above flood levels
►New I-35/80 Interchange
►Incident Management Improve emergency response on I-35/80 and
MLK
►Development of “Urban Reserve”
10
Urban Reserve►Utilize sand and gravel
mines as part of end use plans
►Develop cohesive plan for area
►Urban reserve would provide:
►Floodplain mitigation►Potential wetland mitigation►Expanded green, natural areas►Diverse ecosystems►Complement and connect to
Des Moines River water trail and Neal Smith trail
►Increase natural areas from 2,300 ac to approximately 6,000 ac in this area
11
South End Concepts*
►MLK, Jr. Parkway (Euclid Avenue – I-235):
Improve existing roadway to increase capacity
Improve intersection capacity
►Utilize existing right-of-way
►Streetscape enhancements
* Based upon current study; subject to change
12
Factors to be Considered within EIS: South End
►Des Moines “Complete Streets” policy
►Expand bicycle trail network
►Transit
►Bicycles/Pedestrians
►Economic Impact/Reinvestment
►Preserve Neighborhood Character
►Minimize impacts to existing properties
13
EIS Decision Process
►The Memorandum of Understanding (MOU) will include Des Moines, Polk County, Iowa DOT, and FHWA, with decisions made jointly among those bodies
►The EIS will consider all prudent and reasonable alternatives and study impacts
►Alternatives evaluation, including No Build
►Public Input
►We are seeking Des Moines’ approval of the MOU at this time
