Existing Highway Geometry:

• Broken-back curves

• Curves with radii smaller than accepted minimum

• High accident rates

Existing Radii = 250’

Existing Radius = 230’

Existing Bailey Avenue Alignment

• Replace existing structurally deficient bridges.

• Lessen channel constrictions to improve hydraulic

openings & reduce ice jamming.

• Improve highway geometrics by eliminating broken back

curves and increasing curve radii.

• Maintain two-way, four lane traffic on high volume

commuter route.

Project Goals:

Preliminary Alignments:

11

Proposed Cazenovia

Creek Bridge:

• Single span rigid frame

• Incorporated alignment

curvature

• Existing South & North

abutments to be

removed

12

Proposed Buffalo

River Bridge:

• Single Span

Simply Supported

Girders

• Existing south

abutment to be

removed.

• Existing north

abutment to

remain.

13

Proposed

Bridge Sections:

• 9 composite

plate girders

spaced at 8’-8”

• Cross frame type

diaphragms used

• Public & private

utilities carried

TEXAS AESTHETIC

CONCRETE BRIDGE BARRIER

• Change affected controlling member (Fascia Girder)

• Lightweight Concrete Substituted

• Steel Bridge Railing to Texas Aesthetic Concrete Bridge Barrier.

• Shoring Design Changes – Buffalo River North Abutment• Soil Anchors Changed to Rock Anchors to Quantity

Winter Concreting:

Erection:

28

• Heavy girders picks + long stick lengths = 2 cranes + mid-air splices• Buffalo River Girders = 229.5’ long x 165,000 LB (total wt.)

• Buffalo River “A” Girders = 134.5’ long x 95,000 LB (segment)

Erection:

29

• Bracing of the first girder installed at the Buffalo River bridge.

Bracing was attached to existing adjacent bridge.

Demolition:

30

• Demolition of the existing bridges presented their own

challenges due to the enormous weight of the existing

built-up, riveted girders.• Cazenovia Creek Bridge Existing Girders = 72 Tons

• Buffalo River Bridge Span 1 Girders = 45 Tons

• Demolition of the Buffalo River bridge was further

complicated by the presence of a counterweight that

had the potential to rotate.• Buffalo River Span 2 Girders = 48 Tons

Learning Assessment:

• What was one of the project goals?• Replace existing bridges, improve hydraulic openings,

improve highway geometrics, maintain traffic during construction

• What type of structure was the Proposed Cazenovia Creek Bridge?• Rigid Frame (Tall Integral Abutments)

• What was the percentage railing dead load increase due to the field change from Steel 4-Rail to Texas Aesthetic Concrete Bridge Barrier?• 500% 40
