Spur 408, officially designated as "Patriot Parkway", is a four-mile (6.4 km) connecting freeway between Loop 12 and Interstate 20, completely within the city of Dallas, Texas.

The freeway passes through a generally undeveloped area of Dallas; there are no businesses located anywhere on the route that can provide services to motorists.

It is designated as "Patriot Parkway" since it passes along the eastern side of the Dallas-Fort Worth National Cemetery; however, it is locally referred to as Spur 408.

Spur 408 also passes near Dallas Baptist University, whose athletic teams are known as the Patriots, and The Potters' House, the megachurch pastored by T.D.

On December 12, 2007, the Dallas City Council and the Texas Department of Transportation entered an agreement to install lighting on Spur 408 at a cost of $2.5 million.
