TxDOT
repairs load damage on local bridge
The
State Hwy. 70 bridge over the Salt Fork of the Red River is now open for
traffic after severe damage necessitated emergency repairs to the bridge
last week.
Donley
County TxDOT Maintenance Supervisor Steve Smith ordered the bridge
partially closed at 3:30 p.m. last Tuesday after he discovered one section
of the northbound lane had dropped nearly two inches.
Inspection
of the bridge, located below the Greenbelt Dam, revealed that three huge
pieces of concrete were popped out of the fourth interior bent support
from the north where it joined the I-beams of the bridge span. One beam on
the east side of the bridge was actually twisted out of shape.
Officials
with the Texas Department of Transportation (TxDOT) say that a heavy load
may have been what caused the damage and dropped that section 1 5/8”.
All
truck traffic between US 287 and I-40 was immediately diverted through
Hedley, but one lane of the bridge remained open to passenger vehicles.
Early
Thursday morning, TxDOT crews began repairs to the bridge by driving new
pylons 18 feet into the ground on the east and west side of the damaged
section. The bridge was then lifted and set back down on its new support.
Traffic
was diverted to a temporary road through the riverbed as repairs were
made.
The
bridge reopened late Friday afternoon, according to TxDOT spokeswoman
Barbara Seal.
The
Salt Fork bridge was constructed in 1954, Smith said. The south end washed
out in 1957. It was rebuilt and then
lengthened some time later.
The support that failed
was originally the north end of the bridge but is now located near the
center.
TxDOT
officials say long-range plans call for the bridge to be replaced with
earthen fill because the existence of the Greenbelt Reservoir makes the
bridge “hydrologically unnecessary.”
