SUBJECT: Grant Application Authorization for Traffic Safety Improvement Funding
of the City of Dubuque IA 32 (Northwest Arterial) at Asbury Road
Intersection
INTRODUCTION
The attached resolution provides the authorization for the City of Dubuque to submit
a joint grant application with the Iowa Department of Transportation (Iowa DOT) for
Traffic Safety Improvement Program funding for the City of Dubuque IA 32
(Northwest Arterial) at Asbury Road intersection.
BACKGROUND
Currently the intersection of Asbury Road and the Northwest Arterial is a four-way
signalized intersection with the following geometrics:
1) North side, southbound leg: One left-turn lane, one through lane, and one shared
through/right-turn lane. Protected left-turn signal phasing.
2) South side, northbound leg: One left-turn lane, two through lanes, and one right-turn
lane. Protected/permissive left-turn signal phasing.
3) West side, eastbound leg: One left-turn lane, two through lanes, and one right-turn
lane. Protected/permissive left-turn signal phasing.
4) East side, westbound leg: One left-turn lane, two through lanes, and one right-turn
lane. Protected/permissive left-turn signal phasing.
In April, 2006, and February, 2007, HDR Engineering, Inc. (Omaha, Nebraska)
completed its two-part traffic operations study of the Northwest Arterial Corridor for the
Iowa DOT. The findings indicated that operational and safety concerns have and will
continue to increase with the dramatic growth of traffic volumes in that corridor. The
statistical data of the 2025 and 2031 Dubuque Metropolitan Area Transportation Study
Long Range Transportation Plans validates that the Northwest Arterial at Asbury Road
intersection has a significant "crash interest".
DISCUSSION
The proposed improvements at the Northwest Arterial and Asbury Road intersection
consist of the following additions:
- Dual left-turn lanes to the north side southbound leg of the Northwest Arterial, with
protected-only phasing.
- Dual left-turn lanes to the south side northbound leg of the Northwest Arterial, with
protected-only phasing.
- Right-turn lane on north side southbound leg of the Northwest Arterial.
- Lighting for the intersection approaches to enhance driver visibility.
RECOMMENDATION
I recommend that the City submit a joint grant application with the Iowa Department of
Transportation for Traffic Safety Improvement Program funding for the IA 32 (Northwest
Arterial) at Asbury Road intersection.
BUDGET IMPACT
The summary of the estimated project cost provided by HDR Engineering, Inc. is as
follows:
Demolition & Removal $ 50,565
Pavement/SurFacing 314,180
Earthwork & Grading 12,275
Storm Sewer 34,640
Signalization 40,000
Lighting 150,000
Pavement Markings 31,418
Traffic Control 31,418
Modified Subbase 78,545
Subgrade Stabilization 94,254
Landscaping 47,127
Mobilization 44,221
Contingency 265,327
Total Project Cost $1,193,970
The City is seeking $500,000 (approximately 42%) of the projected $1.2 million from the
Traffic Safety Improvement Program grant. The City is currently evaluating additional
funding resources for the remaining $700,000. With secured funding, it is anticipated
that the construction could begin in April, 2009, with completion in November, 2009.
There is no other fee associated with the application process since the City is utilizing
the services of East Central Intergovernmental Association (ECIA).
ACTION TO BE TAKEN
The City Council is requested to adopt the attached resolution authorizing the filing of
a joint grant application with the Iowa Department of Transportation for Traffic Safety
Improvement Program funding for IA 32 (Northwest Arterial) at Asbury Road
