Lanes to change at Fourteenth Street and South Avenue

Ponca City Now - October 9, 2015 12:18 pm

Traffic lane assignments on the eastbound approach to Fourteenth Street and South Avenue will be revised on Monday morning, October 12 to remove one of the left turn lanes and add a second eastbound through lane.

The existing traffic striping on South Avenue east and west of Fourteenth will be removed on Sunday evening, and the new striping will be installed on Monday morning. The change is being done to better serve the existing turning movements on that approach.

The current dual left turn lanes were installed in 1989 when eastbound left turning volumes warranted the storage space. Traffic patterns at the intersection have changed, and today the eastbound through movement accounts for the heaviest volume of traffic on the approach.

The existing south left turn bay will be used as the new eastbound through lane. The north left turn bay will be lengthened to 150 feet to accommodate peak hour left turning traffic.

Traffic striping on the east side of Fourteenth Street will be changed to accept the additional eastbound through lane. The two eastbound through lanes will taper to one lane approximately 500 feet east of Fourteenth Street.

Some traffic signal modifications will be necessary with this change. The left turn detectors in the south left turn lane will be switched to place a call for the eastbound through movement. The traffic signal heads for eastbound traffic will be modified to properly control the new lane configuration. These changes will be completed Monday morning in conjunction with the striping revisions.

During the time of the traffic signal modification, the intersection will be operated as a four-way stop.

Any questions regarding this project may be directed to Mike Lane, Traffic Engineering Manager, at 580-767-0327.
