3/4 Access Follow-up

By Mike Spack

October 21, 2014

Last week I wrote about a 3/4 access near my home and office that has a lot of signs telling drivers they can’t turn left off of the cross street.  The signs are a waste of money in my opinion.  My wife Jane called me yesterday afternoon laughing.  She just drove through that intersection and a person made the illegal left in front of her!

Maybe five signs will solve the problem?  Nope.  In order for a 3/4 access to be effective it needs to have a splitter island on the minor leg and enough median on the major street to make the move impossible.

p.s.  Thanks for reading honey!
