0% 100% 54 0 0% 0244/1 54Masonry Culvert 0 0%ft

2-span rubble Dakota sandstone arch culvert. Random longitudinal and transverse cracks affecting approximately 5% of the asphalt overlay above the culvert. Debris accumulation present on upstream nose of Wall 2 and in front of Cell 2.

CS3: (1610) Mortar joints at water level deteriorated in all walls and crown. Worst location is located at three-quarters height and up to top of crown with a few areas of missing mortar in arch. Worst locations in Cell 1, Wall 1 (8 Foot) and Cell 2, Wall 3 (52 Feet, Actual = 54 Feet).

(1640) 3 foot wide x 1.5 foot long section of missing and deteriorated floor at inlet of Cell 1. No undermining present (2 Feet).

CS2: (1120) Light efflorescence in the top of both arches leaking through the joints (QUANTIFIED ABOVE -

54 Feet).

0% 0% 0 0 100% 4323/1 4Approach Railing 0 0%(EA)

Approach rails are not long enough and northeast end is sloped and buried. Buffered end protection at northwest and southeast. Flared end at southwest is secured with only (1) bolt. Minor impact damages along north rail.

25% 0% 0 0 75% 3326/1 4Bridge Wingwalls 1 0%(EA)

Rubble Dakota sandstone interlocking with headwall. Large rock riprap at all wingwalls. Previously mentioned crack in the northeast wingwall has been repaired prior to 2021 inspection. Northeast wingwall has 20 square feet of missing stones on top but placement of riprap mitigates any embankment loss. Top 4 stones near the end of the southeast wingwall are loose; mortar is missing and ineffective. Bank erosion at northwest extends behind wingwall 4 feet.

Manmade channel (canal) with regulated flows. Straight alignment through culvert with wide, sandy bottom. Large rock riprap placed at inlets and outlets. Moderate erosion of the northwest bank up to 20 feet long x 10 feet wide x up to 4 feet deep with displaced riprap. Moderate to steep sloped banks (3:1 -

2:1) with grass and brush above normal water level. Minor undercutting and erosion at normal water level.

DATE: 7/13/2017

REVIEWER COMMENTS:

Most recent report dated 03/12/2015 shows Item 113 = 4 and 'toe of the east concrete apron is exposed up to 8 inches'. Per CDOT clarification of Item 113: The code of "5" is to be used for bridge structures that cross canals or other controlled waterways in all cases, unless other findings indicate that a lower code should be used'. Exposure of east apron is considered to be minor scour and not sufficient to lower Item 113 code below "5".

Change Item 113 to 5.
