| *Subject to transportation constraints |
 |
A range of nine M-sections, M2 to M10, are available for use by the bridge engineer to cater for various spans from 16 metres or less up to 28 metres (subject to transportation constraints). Standard web holes (see fig 1) provided at 600mm centers when necessary for threading transverse reinforcement through the bottom of the webs. |
