121st Ave & Springwood Crosswalk Enhancement
|
In FY 1999-2000, the City started a pilot program to install embedded crosswalk
lighting systems at various locations in the City. The first system was
installed on 121st Ave at Katherine/Lynn Street, followed by two additional
systems on Walnut Street (at Grant Ave) and Main Street (at the bridge).
The lighted crosswalk on 121st Ave (at Springwood Drive) was installed in
October 2001. The most recent crosswalk lighting system was constructed on
Bonita Road (at Milton Court) in October 2002.
The light fixtures that are recessed below the pavement surface on 121st Avenue
at Springwood Drive and Katherine/Lynn Street require frequent replacement.
In addition, the road surface needs to be continually cleaned in order for the
lamps to project a beam that is clearly visible in daylight and under the worst
weather conditions. Maintenance of the light fixtures has been difficult, replacement
parts have not been readily available, and continued maintenance of the existing
lighting system is not cost effective.
Lights on 121st Avenue at Springwood are being replaced with a more efficient
traffic lighting system that minimizes maintenance costs while enhancing safe
crossings for pedestrians. A flashing beacon system is replacing the existing
in-pavement non-functioning crosswalk lights. The beacon system is self contained,
wireless, solar powered and utilizes LED technology for the lights, because of
this, the beacon system should provide a long low maintenance solution at this
location. The beacon system includes an early warning beacon and dual beacons at
the crosswalk in both directions of travel along 121st Avenue. The beacons are
highly visible during the day or night. Because the beacons are activated by
pedestrians and not operated on a timed schedule, they should provide an effective
warning to drivers for an appropriate period of time. The existing in-pavement
lights will remain in-place, non-functional. Removal of the lights may take place
at a future time.
