Clinton Street Bridge over the Maumee River ODOT Project - - PowerPoint PPT Presentation

Clinton Street Bridge over the Maumee River

ODOT Project DEF-15-14.77 December 2, 2014 Stakeholder’s 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

Purpose of Stakeholder Meeting

 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

Project Purpose

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.

 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

Existing Bridge

 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.

Study Area

Study Area (Yellow Outline)

 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)

Environmental Concerns on the Project

 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

Alternatives Evaluation

 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.

DEF-15-14.77 Alternatives

Bridge Concept

Actual appearance to be determined later in design process

 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

Factors Affecting Alternative Evaluation

 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.

Bridge Aesthetics (How bridge will look)

Existing Bridge Lighting

 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.

Maintaining Traffic During Construction

 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

Other Project Goals

Existing Sidewalk and Curb Ramp – Southwest Corner

Existing Sidewalk – Southeast Corner

Existing Bridge – Not much room for bikes

 Construction in 2019 (preliminary estimate)  Depends on funding, environmental concerns, right-

• f-way acquisition, and completion of construction

plans  Project schedule updates will be provided as changes in the schedule are known.

Current Project Schedule

 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

• r 2017.

Project Funding

 This meeting is the first in the public involvement process  Additional stakeholder meetings will be held  Public involvement meetings to be held as well  Comments, concerns, or any information you can provide are appreciated!
