General Contracting

Petersen Brothers, Inc. has been serving the Puget Sound and Washington State area as a highway safety contractor for over 50 years.  Our specialties include:


sometimes referred to as W-beam or thrie beam, is a system designed to keep people or vehicles from (in most cases unintentionally) straying into dangerous or off-limits areas.

Pre-cast Concrete Barrier:

Sometimes referred to as jersey barrier, pre-cast concrete barriers are modular concrete barrier employed to separate lanes of traffic.  It is designed to minimize vehicle damage in case of accidental contact while still preventing crossover in the case of head-on accidents.

Also utilized extensively to re-route traffic and protect pedestrians during highway construction, such barriers are increasingly deployed in anti-terrorism roles as both quick fixes and semi-permanent protections against perceived landborne threats.

Guide Posts:

Sometimes referred to as in-ground delineators, guide posts provide delineation between roadway and other surfaces.  They also provide a mounting point for other markings, such as arrows to highlight a roadway curve.

We provide temporary construction and permanent signs, including installation.
