It's also possible to switch to US 40 to avoid the DE I-95 turnpike, if avoiding that is necessary.

I usually stay on I-95 but opt to take the Univ. of Delaware exit in Newark and bypass the $4 toll. It usually works in avoiding the toll backups as well.

Then I get back on I-95, and sometimes stop at Christiana Mall or any of the other big boxes (Best Buy, Staples, etc.) in DE, to buy items tax-free. It sure beats the 7% tax in NJ, or 6% in MD.
