Transcription

1 Clinton Street Bridge over the Maumee River ODOT Project DEF December 2, 2014 Stakeholder s Meeting

2 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

3 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

4 Existing Bridge Deck North End Cracked asphalt is porous. Deicing chemicals leak through to whatever is below it.

5 Existing Bridge Deck South End Holes in asphalt at south end of bridge.

6 Underside of Existing Bridge Superstructure (at curb line) Note concrete cracking. This is caused by reinforcing steel and prestressing strands that are corroding.

7 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.

8 Underside of Existing Superstructure (Mid Span) Another failed strand towards the middle of the bridge

9 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.

10 South Abutment Note deteriorated concrete. Caused by deicing chemical leakage from bridge deck.

11 Existing Pier Note concrete deterioration at sidewalk curb line.

12 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

13 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.

14 Study Area (Yellow Outline)

15 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)

16 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

17 DEF 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.

18 Bridge Concept Actual appearance to be determined later in design process

19 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

20 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.

21 Existing Bridge Lighting

22 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.

23 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

25 Existing Sidewalk and Curb Ramp Southwest Corner

26 Existing Sidewalk Southeast Corner

27 Existing Bridge Not much room for bikes

28 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.

29 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.

30 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 Comments, concerns, or any information you can provide are appreciated!

31 Stakeholder Concerns/Input Comments after the meeting should go to: Jenn Gasser, ODOT District 1, (419) , or Jeff Griffin, Burgess & Niple, (614) , Future project information go to District 1 website, Construction Projects & click on DEF SR 15 Clinton Street Bridge ( ms/projects/defiance15/pages/default.aspx)
