Mechanical traffic spikes (directional spikes, tire spikes) are available in surface mount and flush (in-ground) mount models. The surface mounted models come in 3' sections while the flush mount models come in 6' sections.

Some of the options available for the directional spikes are end caps, latch down, and heavy duty models. Latch down allows the spikes to be recessed into the unit so bi-directional travel can be achieved. A simple tool is used to raise or lower the spikes.
