CGA Engineers was awarded the contract to design improvements for the Rehabilitation/Maintenance of the intersection of a primary arterial street for the City of Tulsa. This project included traffic signalization, street reconstruction, street repairs waterline replacement, and reconstruction of sanitary sewer crossing. Traffic signalization for this project included replacement of traffic signals at the intersection of E. Admiral Pl. and S. Memorial Drive., including all wiring replacement of existing traffic system with video and wireless communication controller. A full signalization wiring diagram for phasing of the lights, design of traffic sequence and removal of existing system was designed. Services also included abstract reports, easement acquisition, topography and right of way surveys as well as utility coordination.
Being in a highly urbanized area with limited right of way, the horizontal layout was modified to closely fit existing conditions while meeting AASHTO turning radii for the design vehicle. All traffic signalization was done per current City of Tulsa traffic standards. The waterline was designed with extensive use of horizontal bores to protect tress and to tie to existing waterline. Handicap ramps and sidewalks were designed to meet ADA standards. A number of driveways were replaced. New traffic striping and marking were placed. Reconstruction of stormwater inlets were included in the design phase. Whee open cuts across driveways were required, high early strength concrete was used to minimize the closer time and inconvenience to the home owners.
