Rehabilitation of the NY 250 Lift Bridge over the Erie Canal - - PowerPoint PPT Presentation

Rehabilitation of the NY 250 Lift Bridge over the Erie Canal Fairport, New York Project Update Meeting February 22, 2018

Project Update Meeting February 22, 2018

Agenda

• Presentation on bridge condition/project

scope/detours/closure

• Questions

Existing Condition

• A four span structure, two multi-girder approach spans, one bowstring truss lift span,
• ne culvert that allows pedestrians to cross under NY 250.

Existing Condition (Cont’d)

• Built in 1914

Existing Condition

• Rehabbed in 1986
• Replaced portions of the floor system in 2013
• The load carrying capacity of the bridge is decreasing due to the weathering and

deterioration of the steel;

• R-posted (normal loads can pass over, heavier loads with permits cannot)
• Mechanical and electrical systems are in fair condition

Existing Condition (Cont’d)

• 36’-10” wide curb to curb
• Carries one lane in each direction
• Pedestrians are accommodated

by the 10’ sidewalks on each side

• f the bridge
• NY 250 has approximately 16,000

Vehicles per Day of which 3% are heavy trucks (480)

Existing Condition (Cont’d)

• The Erie Canal Trail pedestrian

pathway passes under the north portion of the bridge.

• Bicyclists on the Erie Canal Trail

use Liftbridge Lane to cross NY 250

Existing Condition (Cont’d)

• The bridge is showing its age and

needs to be rehabilitated prior to further down posting or having the lifting mechanism stop working with the bridge in either the up or down position.

Rehabilitation Project

• NYSDOT is developing a project to

rehabilitate this bridge.

• The NYSDOT and Canal Corporation will

invest approximately $8.93M in this structure

• Bid opening is scheduled in October 2018.

Goals of the project

• Have a fully rehabilitated structure that will:
• Carry legal loads for many years without load posting;
• Minimize future maintenance/closure in the Village;
• Raise and Lower very smoothly for the life of the bridge;
• Maintain the historical significance of the bridge
• Complete in a fashion that balances construction duration and

economics

Scope of work

Replace:

• The entire floor system;
• Lower chord on the truss and truss members to the “spray line”;
• Gusset plates;
• Electrical and mechanical systems;
• Lifting Frames

Duration of Closure

In order to replace all of the structural members, lifting mechanisms, and electrical systems, we estimate that this bridge will be out of service for 13 to 15 months. Similar lift bridge rehabilitation projects have taken 18 to 21 months of closure but we have identified time saving operations such as:

• Replacing the lifting mechanical systems instead of reproducing portions of a lifting system;
• Concurrently performing work as long as the structural integrity of the bridge is maintained;
• Using time incentives/disincentives for all work once the bridge is closed.

When do you start this work?

• We are proposing to allow the closure of the bridge to begin no earlier than the week of July

8, 2019

• We anticipate the re-opening as early as August 2020.

Detour

• While the bridge is closed, thru traffic

will be detoured using Ayrault, Turk Hill, and Whitney Roads.

• Local traffic will be allowed to travel

right to the project site or essentially very close to the bridge.

• Local traffic will also use Parker Street

however we are currently not signing this as a detour.

• We are currently analyzing the traffic

volumes and movements at the signalized intersections. If reasonable improvements are necessary, we will make them.

Pedestrian Accommodations

• Pedestrians will continue to be

accommodated on the existing pedestrian system. They will have access to all of the parking lots in the village and will walk to their destination as they do today.

• Pedestrians will also be able to use the

Parker Street Bridge which is approximately 750’ from NY 250.

• Erie Canal Trail walkers will be

detoured to Liftbridge Lane. This is the same route as the trail bicyclists.
