3-Sided Culverts
Three-sided culverts have an incredibly long service life and can be used for many of the same applications as box culverts. Like our box culvert, our 3-sided culverts can support vehicular traffic and can typically be installed within a few hours, saving time and money.
Box Bridges
Bridges are essential to the regional infrastructure. As populations continue to grow and transportation needs expand, the necessity for strong, durable bridges increases. Bridges constructed with precast concrete box culverts meet this need, and our products can be manufactured in a variety of configurations to accommodate almost any project. Additionally, precast box bridges can be installed quickly, allowing normal traffic flow to resume more quickly than other solutions.
