Dubuque Street elevation and
Park Road Bridge replacement project
Iowa City Gateway
Dubuque Street serves as Iowa City’s main entrance and key gateway into the community for residents
and visitors. It parallels the Iowa River and carries more than 25,500 vehicles a day between Interstate 80,
the downtown business district and the University of Iowa campus. Park Road Bridge also serves as a critical
transportation link for Iowa City. Together, these corridors provide vital connections for the community’s
safety, commerce, neighborhoods and recreation.
The City of Iowa City has been studying potential solutions to minimize flood impacts on Dubuque Street,
reduce backwater created by Park Road Bridge and make needed infrastructure improvements to the corridor.
The Preferred Alternative includes the design elements derived from Alternative Alignments B and C, which
were presented to the public during previous public meetings. The Preferred Alternative, shown inside this
handout, includes:
• Elevating Dubuque
Street to the 500-year
flood elevation plus
1 foot;
• Using a modified
S-curve between Foster
Road and Mayflower
Residence Hall that
reduces property
impacts along Dubuque
Street;
• Maintaining direct driveway access to Dubuque Street for private drives, parking lots and apartment
buildings in the corridor;
• Relocating, improving and elevating the Ridge Road intersection with Dubuque Street north of its existing
location to line up with the relocated Terrell Mill Park entrance;
• Removing and replacing the existing Park Road Bridge and skewing the new Park Road Bridge
approximately two degrees southward from the existing bridge; and
• Relocating the Dubuque Street and Park Road intersection approximately 60 feet south of the existing
intersection to accommodate the new bridge.
April 2013
The new Park Road Bridge is anticipated to be approximately 450-foot long by approximately 85-foot
wide, three-pier steel box girder bridge. The bridge will be constructed so that the lowest point of the bridge
substructure will provide one-foot of clearance for a 500-year flood to pass under. Once the new bridge is
constructed and open to traffic, the existing Park Road Bridge will be removed in its entirety.

Additionally, the Preferred Alternative includes:
• Constructing Park Road Bridge with five 12-foot lanes to
accommodate dual left-turn lanes for eastbound Park Road to
northbound Dubuque Street vehicular movements;
• Expanding Park Road west of the Lower City Park entrance from
two travel lanes to two 12-foot travel lanes and one 12-foot center
turn lane;
• Maintaining the Iowa River Trial as a 10-foot shared use path west
of Dubuque Street and constructing an 8-foot sidewalk on the east
side of Dubuque Street from Foster Road to Brown Street;
• Maintaining similar drop-off and pick-up access for CAMBUS
patrons at Mayflower Residence Hall;
• Improving shared use path safety and connectivity on the west side of Park Road Bridge to Lower City Park
with a grade-separated crossing;
• Improving and consolidating the Park Road, Riverside Drive and Upper City Park/Templin Road
intersection;
• Realigning (and elevating as necessary) the access drive to Lower City Park with the future Hancher
Auditorium perimeter drive location; and
• Improving Iowa City Transit stops to meet ADA guidelines and provide hard surface connectivity to walks
and paths.
The Iowa City Gateway Project is led by
Iowa City in coordination with the U.S.
Economic Development Administration, the
Iowa Department of Transportation and the
Federal Highway Administration, and in
cooperation with the University of Iowa.
More information about Iowa City Gateway
can be found at: iowacitygateway.org or by
phoning 319-356-5140.
Bicyclists and pedestrians will still
have a shared use path west of
Dubuque Street, as well as a new
sidewalk on the east side.
