When the Woolwich foot tunnel closed for repairs in 2011, it should
have been a routine job. The pathway had been providing pedestrians with
a quick route beneath the Thames since 1912. A century on, a few minor
improvements were necessary.
But Woolwich residents will recall that the refurb of this much loved and much used walkway did not go according to plan. When
it finally re-opened it was 8 months behind schedule, having been
closed for more than a year and a half. What the average Woolwich
dweller doesn’t know, however, are the unusual circumstances behind this
delay.
Mention the 18 month time frame to someone who worked on the Woolwich
Tunnel job and you may be met with a mysterious smile. A year and a half
may have seemed a long time to those who relied on the tunnel for their
daily commute. But for those who were down there beneath the river,
that time-frame has a different meaning. When one contractor tells me he
aged 3 years on the Woolwich job, it is not a metaphor. For, deep down
beneath river and clay, hidden from those above ground, something was
occurring. That something was a time anomaly.
