The 'cause' in causeway : crossing the Avon River at Windsor / [written and designed by J.A. Percy]. : En13-8/28-2008E-PDF

"The stark, rocky causeway arcing across the Avon River at Windsor, Nova Scotia, has been a source of concern to many environmentalists ever since the first boulders tumbled into the roiling tidal waters almost 40 years ago. Many ecological changes, ranging from accumulation of sediments along stretches of the riverbed to decimation of fish stocks, have been attributed to the blockage of tidal flow by this barrage. Over the years, however, even the most ardent environmentalists had more or less resigned themselves to the fact that there was little realistic prospect of undoing such a major engineering project. In recent years, however, the debate about the fate and the effects of the structure has been rekindled. ... To provide a social and economic context for the reignited causeway controversy it may be helpful to review the history of crossings at this site and examine the rationale for, and the manner of, construction of the causeway. It might also be worthwhile to consider some of the benefits and environmental costs of the causeway and how these might be affected by any changes to the structure."--p. 1.
