Concrete

Deck Wearing Surface: 0-None (no additional concrete thickness or wearing surface is included in the bridge deck)

Deck Evaluation:

8.0" concrete slab.

Stay in place metal deck forms.

The deck surface has random minor cracks.

Bent 2 joint is open.

NBIS Condition: 4 Material: 34 - M. Steel Year Painted: 1978 Paint Type: 2 - 1- Lead Chromate Oil Alkyd System

Superstructure Evaluation:

Two span structure with five W33X130 steel beams.

Last painted in 1978, the beams were not cleaned when repainted and still have lead base paint under new paint.

The paint system has faded, has areas where the paint is peeling off and areas of effectiveness loss on the beams and bearings.

The bearings at the abutments have minor corrosion.

Bent 2 bearings have corrosion and pack rust.

Spans 1 and 2 beam ends at bent 2 have areas of corrosion and rust swell with beam 4 being the worst.

Span 1 beam 5 at bent 2 the bearing has up to .2' of the bearing masonry plate unsupported due to a moderate spall beneath the bearing. Now .7' of the masonry plate is now resting on solid cap.

Span 2 beam 1 has areas in the bottom flange with minor pitting.

Span 2 beam 3 at bent 2 the bearing has up to .6' of the bearing masonry plate unsupported due to a large spall beneath the bearing. Only .3' of the bearing masonry plate is resting on solid cap. The bearing sole plate and masonry plates are out of alignment. The masonry plate is 0.75” forward of the sole plate. All other bearings at current temperature are squarely aligned.

Water from the deck drains is corroding the exterior beam flanges and webs.

Shoulder erosion on left and right sides of abutment 3 is causing dirt and gravel to accumulate on the exterior beams. (Needs to be removed)

Special note:

The superstructure was rated a 4 due the lack bearing beneath beam 3 in span 2 at bent 2. Once proper repairs are made to the cap the rating will change to reflect the condition.

Evaluation

Team Lead: Phillip Jennings, Inspection Date: 05/21/2025 County: 129 - Gordon, District: 6, Inspection Area: 6

Substructure Evaluation:

All concrete cap units, abutments are founded on driven steel pile.

Bent 2 is a solid concrete pier wall founded on a spread footing.

Abutment 1 cap beneath bay 4 has a minor spall.

Abutment 1 back walls have moderate spall/delamination areas at the beam ends.

Bent 2 pier wall rear face beneath beam 5 has a 1.0' long x 0.2' wide x 1.0' high spall beneath the bearing.

Bent 2 pier wall forward face beneath beam 3 has a a large spall measuring 5.7’ long x .6’ wide x 3’ high. The spall measured from the top on the right side of the bearing masonry plate shows up to .6' of the bearing unsupported and on the left .55’ of the masonry plate is unsupported. Only 0.3’ of the bearing masonry plate on the right side and 0.35’ on left side is supported by a solid cap. The right anchor bolt and nut is still tight, this appears to be what is holding the rest of the delamination area to the cap. The left anchor nut is in place but has sheared. The masonry plate dimensions are .917' x .917' or 11” x 11” .

Bent 2 footer is exposed up to 0.9'.

Drift located beneath span 2.

The forward bank has minor scour.

Shoulder erosion on left and right sides of abutment 3 is causing dirt and gravel to accumulate on the exterior beams. (Needs to be removed)

This Bridge: 5 - Initial/Existing Inventory, does not replace any

Built in 2002 as a local county design using salvaged D.O.T. steel.

Replaces old serial 129-5057-0.

County road 304 Slate Mine Road.

The rear approach roadway is settled up to 1.5”. (Partially leveled with cold mix) Span 1 Left side bridge rail end at abutment 1 has a 2.0’ high x 0.5’ wide x 0.1’ deep spall.

Bridge rail has minor cracks with some efflorescence.

5/21/2025 Due to lack of bearing area beneath beam 3 in span 2 at bent 2. Caused by a large spall spall beneath the bearing masonry plate. It was determined that the bridge should be closed until repairs have been made. On 5/21/2025 Rusty Hogan, Gordon County Interim Public works Director was verbally notified of the Bridge Closure and meet with inspectors at the bridge.

Special Notes:

The rear left bridge rail does not have transitions or guardrail, leaving a dangerous blunt end exposed. The forward right bridge rail does not have a proper transition.

Bridge inspected beyond 24 months to optimize schedule.
