STR235, G.O. Bonds
ADDITIONAL INFORMATION:
The proposed improvement consists of widening the
north and south approaches on Merle Hay Road in order to provide left turn
lanes. The current pavement width of 49’
would be widened to 65’. A raised median
would be installed on Merle Hay Road within the vicinity of the
intersection. New traffic signals with
backplates would also be installed, including north-south left turn
phasing. A 10’ clear zone would be
established within the limits of the project.
This intersection ranked 55th on the state’s 2001-2005
“Statewide Intersection Candidate Listing.”
Due to its high crash experience, this location was previously reviewed
in a study that was commissioned by the Iowa DOT Traffic Safety Office.
On March 24, 2008, by Roll Call No. 08-464, the City
Council approved the Predesign Agreement for Merle Hay Road (Iowa 28) Widening
at Urbandale Avenue. The predesign agreement
authorized the City to perform the survey, design, environmental clearance, and
right-of-way acquisition phases of the project.
City staff has completed the survey, preliminary design, and
environmental clearance phases of the project, including an updated cost
estimate. On January 29, 2009, a public
informational meeting for the project was held at Hillis Elementary School.
The total project cost for the widening project was
originally estimated to be $2,000,000. The
updated cost estimate for the project, based on preliminary design, is
$2,360,000. $750,000 in Highway Safety
Improvement Program funding, $400,000
in Iowa Clean Air Attainment Program funding, and $500,000 in Traffic Safety
Improvement Program funding have been approved for this project. The remaining costs will be split between the
Iowa Department of Transportation (55%) and the City of Des Moines (45%). This addendum to the Predesign Agreement
increases the estimated project cost and identifies the various funding sources
to be utilized to complete the project. Construction of this project by the Iowa DOT
is anticipated in 2010.
