Safeguarding and strengthening of the Exe Viaduct, Exeter

About this event

Exe Viaduct is an existing structure that carries the M5 over the River Exe, east of Exeter. It is 692m long, composed of two independent externally post tensioned concrete box girders.

In 2016 during an inspection a number of post tension strands were found to have broken. Further investigations found significant corrosion to the strand anchorages and loss of post tensioning force. What followed was a series of safeguarding works, weight restrictions, and finally strengthening.

This talk will detail the investigations, decisions and works undertaken over the last two years, and why the cones have been out for so long!

Refreshments will be available from 18:00 with the talk beginning at 18:30
