FOR RAMPS WITH SHARP CURVES OR MULTIPLE LANES, RAMP SIGNS MAY BE PLACED

(1) SIGN 43 REQUIRED WHEN RAMP WIDTH IS REDUCED.
(2) SIGN 13 SHOULD BE PLACED ON THE RAMP TO PROVIDE ADEQUATE VISIBILITY OF
MAINLINE TRAFFIC.
(3) THE LOCATION OF THE SIGN SEQUENCE AND MERGE TAPER SHOULD BE ADJUSTED SO THAT THE
ARROW PANEL LOCATION IS NOT CONFUSING TO MOTORISTS ON THE RAMP.
(4) FOR WORK ZONES WHERE DEVICES ARE IN PLACE OVERNIGHT, USE TRIM-LINE CHANNELIZERS.
