Photo 3 Cracking across the road at the down slope end of the

island. Note the

pronounced dip in the road at this location. This dip has worsened since 2005. Photo 4 Cracking across the road at the down slope end of the

island. There is a

pronounced dip in the road at this location, particularly in the left / down hill lane.

Photo 7 Erosion along the down hill side of the road near the cracking noted in photo 6. Downhill rill / minor gully erosion in photo 8 below is at the far end of the erosion, adjacent to the cracking in the road (arrow). Photo 8 Erosion down slope from the road, near the cracking in photo 6 and the erosion noted in photo 7.

Photo 9 Overview of the slope below the road. There are no significant changes

n the slope.

Photo 11 South side of the

verpass, showing

the gabion mat-lined

ditch. The gabion

mats and check drop have collapsed locally, indicating erosion under the

lining. The situation

does not appear to have worsened significantly since 2005. Photo 12 The south west corner of the bridge

structure. There has

been no significant change at this location.

Photo 13 Looking south along the rail line. Note the separation between the piers and concrete slope facing

n the right side of

the rail line. The separation does not appear to have changed significantly. Photo 14 Looking north along the railway line. Note the bulge at the base

f the concrete slope

facing.

Photo 15 Looking south across the highway at the joint between the bridge deck and the

abutment. There

does not appear to have been any significant change at this location. Photo 16 Bearings and retrofitted restraining plates at the east side of the overpass.

Photo 17 Detail of the bearings, showing apparent movement between the bridge deck and abutment, as shown by movement between the two halves of the

bolt. Each of the

bearings shows the bridge deck has apparently moved towards the NW (or the abutment has moved to the SE). Photo 18 Looking south along the east abutment of the overpass, at the NE corner. Note the cracking in the concrete abutment.

Photo 19 Piers on the east side

f Shaftsbury Trail,
n the east side of

the overpass. Note cracking on the uphill / east side, and the gap at the west side. Photo 20 Gap at the base of the piers on the east side of Shaftsbury

Trail. Note that the

sense of movement is opposite from those piers on the west side of the rail line – in both cases, the gaps are at the down slope side.
