City Engineer Gus Psihoyos is recommending to set February 7, 2011 as the date for a
public hearing on the North Cascade Road Bridge Construction Project (Phase II of the
Southwest Arterial Project).
The preliminary engineering design phase was completed in March, 2008 and the
Southwest Arterial project is now proceeding with the final engineering design phase,
right -of -way property acquisition and archaeological and cultural resource phase III
mitigation work.
On August 16, 2010 the City Council approved the award of the North Cascade Road
Reconstruction Project (phase I of the Southwest Arterial) to C.J. Moyna & Sons, Inc. of
Elkader, Iowa in the amount of $1,591,521.32. This phase of construction provides for
the reconstruction (grading & paving) and realignment of North Cascade Road from
about 0.6 miles south of the Storybook Hill Children's Zoo to 0.1 miles north of the zoo.
The stage I grading (Bridge abutments) was completed in November which will allow
the new bridge construction to begin in April 2011. Following completion of the bridge
work, stage II grading & paving will resume and is anticipated to be completed by early
fall of 2011.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION
The purpose of this memorandum is to provide the City Council with information related to
the North Cascade Road Bridge Construction Project (Phase II of the Southwest Arterial
project) and request that a date for the public hearing be established.
BACKGROUND
Dubuque

AU- Amaica City

2007
The preliminary engineering design phase was completed in March, 2008 and the
Southwest Arterial project is now proceeding with the final engineering design phase, right -
of -way property acquisition and archaeological and cultural resource phase III mitigation
work.
Additionally, the City is evaluating construction phasing alternatives for completing
components of the project with currently available federal, state and local funding. To
maximize available funding, the City is preparing to move forward with several side road
construction projects that would allow for Southwest Arterial improvements to be made that
would provide immediate public benefit and would provide significant efficiencies and cost
savings on the future grading and paving of the four -lane Southwest Arterial corridor
between Highway 151/61 to Highway 20.
On August 16, 2010, the City Council approved the award of the North Cascade Road
Reconstruction Project (Phase I of the Southwest Arterial) to C.J. Moyna & Sons, Inc. of
Elkader, Iowa, in the amount of $1,591,521.32. This phase of construction provides for the
reconstruction (grading & paving) and realignment of North Cascade Road from about 0.6
miles south of the Storybook Hill Children's Zoo to 0.1 miles north of the zoo. The stage
grading (bridge abutments) was completed in November which will allow the new bridge
construction to begin in April 2011. Following the completion of the bridge work, stage II
grading & paving will resume and is anticipated to be completed by early fall of 2011.
Other side road construction projects that are currently in the design stages are the
English Mill Road reconstruction and the Military Road reconstruction projects. Both the
English Mill and Military Road reconstruction projects will include the construction of new
bridges which will allow the future Southwest Arterial to cross under each of those side
roads.
DISCUSSION
The realigned section of North Cascade Road will have a new bridge constructed which
will allow the future Southwest Arterial to cross under North Cascade Road. The new
bridge project will provide for the construction of a 272 ft. x 44 ft. pretensioned prestressed
concrete beam bridge which will include a 10 -foot wide paved shoulder that would
accommodate bicycle and pedestrian use. The new bridge will also include architectural
enhancement treatments that will include native Dubuque limestone textured piers, pier
caps, abutment walls and barrier rails. The bridge will also have architectural piers that
extend above the bridge deck, along with decorative LED roadway lighting and decorative
bridge railing. Attached is a graphic rendering of the North Cascade Road Bridge and the
proposed architectural enhancement treatments which will be a consistent design theme
for the future English Mill and Military Road bridges.
Once the North Cascade Road, English Mill and Military Road projects are completed and
construction of the Southwest Arterial begins, citizens and vehicular traffic using those side
roads will not be impacted while construction work occurs under each of those side roads.
