DEPT:PW
SUBJECT:2024/25 SOUTH 16TH STREET ROADWAY WIDENING
COUNCIL ACTION FORM
BACKGROUND:
South 16th Street is a Minor Arterial, two-lane rural cross section roadway from University Boulevard
east to the Veterinary Medicine Trail where it widens to four lanes which extends to the intersection
with South Grand Avenue.
While this section of the roadway is owned by Iowa State University, the staff has recommended,
for this one instance, that the City will pay for this improvement since the City's extension of
Grand Avenue into S. 16th has increased the traffic volume and negatively impacted the
intersection operations at S. 16th and University Blvd. Following construction, the roadway and
trail will be owned by the City of Ames in a roadway easement which will give the City full control and
access.
This project will include widening South 16th Street to four lanes from University Boulevard to
the Veterinary Medicine Trail, transforming the roadway into an urban cross section with curb
and gutter. The proposed project also includes extension of the box culvert at Worrell Creek and
a multi-use trail along the south and north sides of South 16th Street from University Boulevard
to the Veterinary Medicine Trail.
This project will have a May 20, 2025, letting conducted through the Iowa Department of
Transportation (DOT), which is a requirement of using the MPO/STP funding. To accommodate the
ISU academic calendar and football season, the project will be constructed in two phases.
This project was initially included in the DOT bid letting on March 18, 2025; however, it was
discovered that a required approval step had been missed that would not have allowed the City to
accept the bids. Once staff discovered this error, and following consultation with the DOT Office
of Contracts, the bids that were received were not opened nor read aloud. The project was able
to be moved to the May 20, 2025 bid letting with the proper approvals now in place through this
council action.
The summary of the estimated revenues and expenses for this project are shown below.

PUBLIC OUTREACH:
Throughout the design process, staff from the City of Ames and Shive Hattery, the consultant design
engineer, conducted multiple meetings with representatives from Iowa State University (ISU). ISU staff
coordinated internally with both the College of Veterinary Medicine and the Department of Athletics to
communicate all proposed design changes and project phasing.
At the 95% design completion stage, City and Shive Hattery staff held a focused meeting with the
College of Veterinary Medicine to review all phases of the project and discuss how traffic access
to their facilities would be maintained throughout construction. Feedback received during this
meeting was reviewed and incorporated into the final project design.
ALTERNATIVES:
1. Approve preliminary plans and specifications for the 2024/25 South 16th Street Roadway
Widening, and establish May 20, 2025, as the date of letting and May 27, 2025, as the date of
report of bids.
2. Do not approve this project.
CITY MANAGER'S RECOMMENDED ACTION:
This project will be let by the Iowa Department of Transportation (DOT), which is a requirement
of using the MPO/STP funding. Approval of the plans and specifications will continue to keep this
project on the Iowa DOT's May 20, 2025, letting schedule. Therefore, it is the recommendation of
the City Manager that the City Council adopt Alternative No. 1, as described above.
