Update, May 19: the closure is now scheduled to begin on Tuesday, May 24.
For those cyclists accustomed to accessing the Don Valley, the Brick Works or Todmorden Mills via Pottery Rd. a change of route will soon be required.
The City expects reconstruction of Pottery Rd to last from Monday May 16 to September 6—the whole summer! (Exact dates will probably change though). An alternative route into the Don Valley is Beechwood Drive (at Broadview and O’Connor; see Google Map).
From the official Construction Notice (download PDF):
Local business access will be maintained (although only from one end of Pottery Rd, access either from Bayview Ave or Broadview Ave), and pedestrian access from Broadview Avenue (to Fantasy Farms & Todmorden Mills) will also be maintained. However there will be no through traffic on Pottery Road during construction… Work will typically take place from 7:00 a.m. to 7:00 p.m. from Monday to Friday, with work after hours and on weekends as required.
There’s no mention to what extent construction will affect (north-south) traffic along the Don Valley recreational trail.
Once reopened in the Fall the rehabilitated Pottery Rd. will feature a 2 meter wide segregated, shared pathway on its western flank (much like it does presently); and bicycle friendly redesigns of the Pottery Rd pathway’s line beneath the DVP overpass as well as the Don Valley Recreational Trail/Pottery Rd. intersection.
