Columbia County Infrastructure

• Columbia County– Northeastern reach of Region 8

– County road maintained = 270+ centerline miles

– County bridges maintained = 137•52 located on county roads

•85 located on town highway

Columbia County Infrastructure

• Bridges– 15 = Reduced load postings

– 6 = Scour critical

Columbia County Infrastructure

• Large culverts– Large culvert structures maintained

= 105•Defined as structures from 5 feet to

just under 20 feet

•Located on county roads only

Columbia County Infrastructure

Total structures County is responsible for

242

Columbia County Bridge Program

• Thru 2014: 7 locally administered, federal aid bridge replacements

• Thru 2011: 4 locally funded bridge replacements

• In 2007: newly instituted, “dedicated” 4-person bridge maintenance/repair bridge crew

Columbia County Bridge Program

• But the County is also required to respond to structure needs due to sudden changes…

Project Locations and Descriptions

Project 1:CR 34 over Hollow Brook

• Town of New Lebanon

CR 34 over

Hollow Brook

CR 34:Pre-Replacement

• Structure Type: two distinct and abutting structure types– Upstream half of structure:

Dry-laid stone masonry arch

Carrying original road alignment in 1800’s (spring line span = 10.5’)

CR 34:Pre-Replacement

• Structure Type: two distinct and abutting structure types– Downstream half of structure:

Concrete superstructure on tall abutments

Realigned roadway in 1946 (span = 17.5’)

CR 34:Pre-Replacement

• In constructing the concrete structure– The stone arch was utilized to

retain the roadway embankment– Result = A single structure integral

and reliant upon the two abutting components

CR 34:Timeline

• Summer/Early Fall 2004: County subjected to multiple severe storms and flooding events, including hurricane remnants traveling up the eastern seaboard

• 8/29/04 to 9/16/04: Storms resulted in flood damage to CR 34 structure

CR 34:Timeline

• 50% of Stone Arch Portion Collapsed:– Reducing structure hydraulic

opening

– Severely compromised roadway embankment and fill on remaining structure

CR 34:Timeline

• 50% of Stone Arch Portion Collapsed:– Stone deposition in stream now

directing flow at remaining arch components

CR 34:Timeline

• Failure Mode:– Structure Type/Size – Flow

Constriction

– Passage of Excessive Flood Flows

– Alignment to Stream Flow

CR 34:Timeline

• FEMA declares county as disaster eligible under FEMA disaster No. 1564 DR NY

• Project actions, design and construction funding by federal and local dollars

CR 34:Timeline

• B&L retained to perform preliminary and final design, and construction support services: Fall 2004

• Coordination w/SEMO for funding assistance: final report submitted May 2005

• Final design/ROW acquisitions completed: April 2006

• Bidding/award:- May-July 2006

CR 34:Timeline

• Construction Contractor: A. Colarusso & Son, Inc.

• Construction Begins: September 2006

• Construction Shutdown: October 2006-June 2007 due to in-stream work restrictions

• Construction of replacement structure completed: October 2007

Project 2:Wire Road over Klein Kill

• Town of Livingston

CR 34 over

Hollow Brook

Wire Road over

Klein Kill

Wire Road: Pre-Replacement

• Structure Type:– Low volume roadway, joining CR 10

and CR 31

– Superstructure - 32 foot, single span jack arch

– Substructures - masonry abutments founded on rock

– Year built - 1935

Wire Road:Pre-Replacement

• Structure Type:– Begin right wingwall replaced with

concrete wingwall/tie-back system -1989

– Remaining wingwalls stone masonry construction

Wire Road:Timeline

• Early Spring 2004, Town of Livingston Supervisor observed major longitudinal roadway cracking at the end of bridge approach

• End left wingwall shifted outward, resulting in roadway longitudinal crack formation, 5’ in from the edge of rail

• Immediate determination for road closure until actions can be taken

Wire Road:Timeline

• Failure Mode:– Type of Construction/Age

– Overload or Excessive Runoff

– Sudden Shifting of Wall (Instability)

Wire Road:Timeline

• B&L retained to perform preliminary and final design, and construction support services: Spring 2004

• Final design complete: May 2005• ROW negotiations: May-December

2005• ROW completed: December 2005

Wire Road:Timeline

• Bidding/Award: January – May 2006

• Construction Contractor: Wm. J. Keller & Sons Construction Corporation

• Construction of replacement structure completed: October 2006

County Route 34 Structure Replacement

CR 34: Design/Construction Issues and Obstacles

• Monitoring of roadway for any continued deterioration encroachment, until replacement structure completed

CR 34: Design/Construction Issues and Obstacles

• Monitoring of roadway for any continued deterioration encroachment, until replacement structure completed

• Coordination with FEMA/SEMO to allow for full replacement

CR 34: Design/Construction Issues and Obstacles

• Coordination with FEMA/SEMO to allow for full replacement– Original Funding - $90,000 for Stone

Arch Reconstruction

– Would not correct Hydraulic or Structural Issues

CR 34: Design/Construction Issues and Obstacles

• Coordination with FEMA/SEMO to allow for full replacement-

Two Feasible Alternatives1. Wingwall Replacement

2. Full Structure Replacement (Recommended)

FEMA Funding -$220,000 for Alt. 1

CR 34: Major Issues and Obstacles

• Massive structure removal of the tall, concrete structure section

• In-stream permitting restrictions

CR 34:Major Issues and Obstacles

• Massive Structure Removal of the Tall, Concrete Structure Section

• In-Stream Permitting Restrictions • Tie-in with Varying Rock

Topography

CR 34:Structure Replacement

• Replacement Structure = precast concrete 3-side rigid frame

• Span = 18’ clear span, 19’-10” along skew

• Out-to-Out Width = 45’-3”• Height = 10’ frame rise, 25’ streambed

to roadwayFinal Construction Cost = $540,000

Wire Road Bridge Replacement

Wire Road: Major Issues and Obstacles

• Coordination with adjacent landowners opposed to the project/acquisition of right-of-way

• Coordination with three overhead utility lines and the need to relocate interfering poles

Wire Road: Major Issues and Obstacles

• Considerations for re-use or retention of original abutment stones

• Two distinct foundation types at each abutment

Wire Road:Bridge Replacement

• Replacement Structure = P/S box beam

• Span = 80’-0”• Out-to-Out Width = 28’-0”Final Construction Cost = $615,000

Summary

• Sudden Structure Failures• Emergency Response Actions• Use of Local (County) Funds• Design/Construction Challenges
