Photo 1Looking west (towards Fox Creek). Approximately 20-30mm settlement (3 years after removal of

surcharge and grading completion) may have occurred at approach slabs (both sides) of bridge and was smoothed-off with pavement patching by AIT maintenance.

Photo 2Looking west (towards Fox Creek).

Alligator crack pavement distress (at west approach to bridge) at inside lane of eastbound lane along wheel path.

Pavement distress located (along eastbound lane) at about 300m west of approach slab to bridge.

Photo 3Northeast corner of bridge headslope (eastbound lane). An area of exposed sandblanket (encapsulated with non-woven geotextile) will require topsoiling and seeding to provide

vegetation growth.

Photo 4Northwest Sedimentation Pond

- Wetland growth environment established- Gabion (dam) provide 0.7m (minimal) free board for sedimentation pond water and sedimentation

storage volume- Upstream soil exposure areas (cut slope and ditch constructions of previous disturbed soil)

stabilized with good vegetation growth; soil erosion as a source of siltation no longer a concern- As wetland vegetation is established over NW pond, the disturbance by machinery for clean-out of

silt will cause more damage than benefit- Over-extraction of silt will affect the base sand drainage blanket below the approach fill

Photo 5Outfall riprap channel from NW pond

- Clean and good water quality observed- Intermittent gabion barrier (along channel) in good condition

- Erosion protection (permanent) measures (vegetation, sedimentation pond, gabion barrier, riprap channel) is performing well and successful

- Temporary siltation fence can be dismantled

Photo 6Iosegun River main channel

- Flood plain deposit of silt from normal annual river flooding events- It is important to recognize river siltation is a natural occurrence along this river floodplain
