Clinton Street Bridge over the
Maumee River
ODOT Project DEF-15-14.77
December 2, 2014
Stakeholder’s Meeting
Purpose of Stakeholder Meeting
 Discuss the project and why it’s happening
 Describe the process that’s used to determine what
gets built
 Share factors that will influence the proposed design
 Identify stakeholder concerns
 Obtain stakeholder input
Project Purpose
 Address deteriorated condition of existing bridge
 Existing bridge is safe, but has some things that need
addressed as part of this project
 Existing bridge deck (what traffic travels on) and
superstructure (what supports the deck) have
deteriorated
 Existing abutments (ends of the bridge) and piers (middle
sections of the bridge) support the superstructure and
have also deteriorated to varying degrees
Existing Bridge Deck
– North End
Cracked asphalt is porous.
Deicing chemicals leak through to
whatever is below it.
Existing Bridge Deck
– South End
Holes in asphalt at south end of
bridge.
Underside of
Existing Bridge
Superstructure
(at curb line)
Note concrete cracking. This is
caused by reinforcing steel and
prestressing strands that are
corroding.
Underside of Existing
Superstructure
(End Span, South
End)
Eventually the concrete breaks
away completely, exposing the
corroded strands, which can then
fail and break away themselves.
Underside of Existing
Superstructure (Mid
Span)
Another failed strand towards
the middle of the bridge
Underside of Existing
Bridge
Superstructure
(End Span – North
End)
Concrete has cracked and broken
away at other bridge locations as
well. Cause for this cracking?
Same as other areas on bridge reinforcing steel and strands that
are corroding.
South Abutment
Note deteriorated concrete.
Caused by deicing chemical
leakage from bridge deck.
Existing Pier
Note concrete deterioration at
sidewalk curb line.
Existing Bridge
 Was originally built in 1932
 Six spans, total length approximately 489 feet
 Rehabilitated in 1980
 New superstructure
 Existing piers and abutments remained and were
repaired
 48 feet face to face of curb (4-12 ft. lanes)
 5 ft. 6 in. sidewalks
Study Area
 Includes the bridge and the next two intersections
north and south of bridge
 Clinton Street intersections with High Street, River
Drive, Fort Street and First Street
 Engineering and environmental studies are
performed within the study area
 Larger than the actual project work limits
 Why? Actual project work limits have not yet been
determined.

Environmental Concerns on the
Project





Circle K Gas Station
Former gas tanks along Clinton Street
Pontiac and Fort Defiance Parks
Maumee River and mussels
Several structures over 50 years old (none eligible for
the National Register of Historic Places)
 One archaeological site (southwest corner; destroyed
according to State Historic Preservation Office)
Alternatives Evaluation
 Engineering and environmental studies are conducted
to help determine feasible alternatives and pros/cons
associated with them.
 Alternative evaluation concludes with a Feasibility
Study, which identifies a Preferred Alternative
 Feasibility Study to be submitted to ODOT later this
month
DEF-15-14.77 Alternatives
 New four lane bridge on existing piers (similar to
existing bridge)
 New five lane bridge on existing piers
 Allows southbound left turn from Clinton Street to River
Drive.
 New four (or five) lane bridge on new piers
 All alternatives have wider bridge sidewalks and
dedicated bike lanes on bridge.
Bridge Concept
Actual appearance to be
determined later in design
process
Factors Affecting Alternative
Evaluation








Construction cost
Traffic safety/congestion
Maintenance of traffic during construction
Environmental impacts
Adjacent property impacts (public and private)
Utility impacts
Future maintenance costs
Inspection of existing bridge piers in November 2014 will
determine if their reuse is feasible and cost-effective
Bridge Aesthetics
(How bridge will look)
 Actual appearance of new bridge is determined in the
next phase of design.
 City preference is current bridge lighting
 Existing pier reuse will affect aesthetics
 Stakeholder and public comments will be considered
when deciding how the new bridge will look.
Existing Bridge
Lighting
Maintaining Traffic During
Construction
 Detrimental effects of traffic detours are understood.
 Goal is to maintain at least local traffic during
construction.
 Local traffic – a trip that begins or ends in Defiance
 How well the alternatives studied meet this goal will
be part of the Feasibility Study.
Other Project Goals
 Improve access to be consistent with Americans with
Disabilities Act (ADA) guidelines
 Improve pedestrian safety on bridge
 Current standards call for 8’- 0” minimum sidewalk
width in commercial areas
 Incorporate bicycle accommodations into project
design
 Proposing 5’- 0” dedicated bike lanes on bridge adjacent
to each sidewalk
Existing Sidewalk and
Curb Ramp –
Southwest Corner
Existing Sidewalk –
Southeast Corner
Existing Bridge – Not
much room for bikes
Current Project Schedule
 Construction in 2019 (preliminary estimate)
 Depends on funding, environmental concerns, rightof-way acquisition, and completion of construction
plans
 Project schedule updates will be provided as changes
in the schedule are known.
Project Funding
 Funding will be secured when Preferred Alternative is
known.
 ODOT has several funding options.
 Funds used will be suited to the type of project being
constructed.
 Right-of-way acquisition anticipated to begin in 2016
or 2017.
Stakeholder Concerns/Input
 This meeting is the first in the public involvement
process
 Additional stakeholder meetings will be held
 Public involvement meetings to be held as well
