Development in the area of Chandler Road/RM 1431, IH -35, and Westinghouse Road.
This increase in scope will allow for the design to include a turnaround structure at
Westinghouse Road, widening Chandler Road /RM 1431 overpass to a six -lane structure,
and ancillary roadway work to align with the bridge widening. Miscellaneous acceleration
and deceleration lane work to improve traffic flow, extending the north bound frontage
road to Westinghouse Road and associated intersection improvements.
Funding:
Cost: $418,431
Source of funds: 4B Corporation (1/2 cent Sales Tax)
Outside Resources: HDR Engineering, Inc.
Background Information:
The original scope of this project included the reversing of the on and off ramps at
Chandler Road, construction of a turnaround structure at Chandler Road, widening of the
northbound frontage road in the vicinity of the Simon/Chelsea Development and
intersection improvements on Chandler Road. The original contract with HDR Engineering
for the design of this work was approved by the Council at their March 11, 2004 meeting.
