For other installations use a 36-inch inner tube and an 18-inch out er tube with soil stabilization fins.

634.3Construction

(1)Obtain the engineer's approva l and locate underground facilities before installing sign posts. Do not

install sign posts until the finished grade is established.

(2)Set and laterally position posts for supporting roadside signs as specified in 637.3.3.2 . Erect posts in a

true vertical position. Orients ign posts as the plan details show to ensure that pos ts will yield or break on impact as designed. For installations in concrete or asphalt, use box-outs as the plan details show.
