The Industrial Ring Road Project includes two crossings the Chao Phraya River, Bangkok with cable-stayed bridges of navigation spans of 398m and 326m. The Project has three approach structures, with a central peninsula interchange which connects the west approach to the main north-south route. The interchange is located between the two main bridge structures, which imposed tight geometrical constraints upon both the arrangement of the cable-stay back spans and the interchange itself. All foundations were 1.5m diameter bored piles extending to 60m depth. The main navigation spans were of steel composite construction whereas the back spans were constructed in pre-stressed concrete. The main bridge featured slender towers with a diamond configuration.
