The Pleasant View School Walkover over Pleasant Grove Road is a
single‐span aluminum constructed in 1974. The walkover is in generally good condition.
SUPERSTRUCTURE
At the west stairs, the west end of the bottom two stair treads are dented and damaged. The bottom
tread has a welded repair on the east end. The seventh tread from the bottom is damaged. There are
slight scrapes and dents at the bottom of both stringers. At the east side of the upper stair run, the
fencing is disconnected along the south vertical edge and at the top at the south end. The concrete is
spalling under the bottom of the west stair stringer.
At the east stairs, there is a small scrape at the base of the west stair stringer and one broken anchor
bolt. The intermediate platform pedestrian fencing fabric was installed sideways so that the twisted wire
ends are oriented vertically along both sides.
Many of the wire ties at the bottom of the pedestrian fencing are missing (44 total counted). One bolt is
missing from the underclearance sign on the south face of the main truss. At the west main truss span
support, the decorative anti‐climb shield is missing on the east face.
There are utility wires under the truss at the east end. They were not touching at the time of the
inspection, but there are scrape marks on the bottom of the south bottom chord.
FOUNDATIONS
At the west stair foundation pedestal, there are leaching map cracks. There is a large crack on the west
face. At the west main span foundation pedestal, there is map cracking throughout. There is a spall on
the southeast corner with incipient spalls at the southwest, northeast and northwest corners. The grout
is disintegrating under the column base plates.
The east stair foundation pedestal is in mainly good condition. There are cracks in the grout under the
column base plate. At the east main span foundation pedestal, there are some leaching cracks. There are
cracks in the grout under the column base plates.
RECOMMENDATIONS:
Chip and repair spalls at foundation pedestals.
Replace grout under column base plates as required.
Reconnect loose fencing at upper stair run of west stairs.
Replace fencing that was installed sideways at the east stairs.
Replace missing wire ties for the pedestrian fencing.
