SUBJECT: REQUESTED REMOVAL OF "NO U-TURN SIGN ON TUSTIN RANCH ROAD AT
IRVINE BOULEVARD
RECOMMENDATION:
Receive and file.
BACKGROUND:
The City Council, at their meeting of October 151 19901 requested an
investigation into the possible removal of the "No U -Turn" sign for
northbound Tustin Ranch Road at Irvine Boulevard.
A review of the subject intersection revealed that the "No U -Turn" sign
cannot be removed due to the presence of a right turn overlap (this is where
the right turn on Irvine Boulevard receives a green arrow at the same time
Tustin Ranch road receives a green arrow for left turns) arrow on Irvine
Boulevard. Although right turn volume off of Irvine Boulevard is currently
light, as soon as the Tustin Ranch Road interchange with the Santa Ana
Freeway is completed the right turn demands are anticipated to increase
dramatically.
The traffic signal at Irvine and Tustin Ranch Road has been designed to
accommodate the freeway interchange traffic as well as the anticipated growth
in the Tustin Ranch area.
The removal of the "No U -Turn" sign at this time would have only a minor
impact, but in the future will have adverse effects.
DISCUSSION:
The Tustin Ranch Road Over -crossing at the Santa Ana Freeway scheduled
completion dates are as follows:
March 1, 1990 - Freeway northbound off -ramp and southbound on-ramp to be
completed.
October, 1992 - Northbound on-ramp and southbound off -ramp to be completed
