Slack Brook culvert, view north, 21 October 1996

Slack Brook culvert, view north (see all photos of the same view)

The level of Slack Brook was altered significantly in order to pass under the new motorway formation, which required a long length of the brook south of the motorway to be re-graded. The culvert carrying the brook across farmland, to rejoin its original course, is seen here, almost complete.
