For the SR 520 Program, we integrate environmental considerations into our planning and design phases to reduce the environmental effect of the rebuilt corridor. Masonry arch bridges use a quantity of fill material (typically compacted rubble) above the arch in order to increase this dead-weight on the bridge and prevent tension from occurring in the arch ring as loads move across the bridge. The arch is in compression, in contrast to a suspension bridge where the catenary is in tension. Exceeded by the masonry arch Trezzo sull'Adda Bridge from 1377 to 1416, with main span of 72m.

We plan, design and construct our projects with the goal of limiting their environmental effects or avoiding them altogether. Rather than repeat this complex process every time a bridge is to be designed, standards authorities specify simplified notional load models, notably HL-93,[65][66] intended to give the same load effects as the characteristic maximum values.
