Two-way cycling is now allowed on the north bank of the Grand Canal between La Touche Bridge at Richmond St/Rathmines Road and Harolds Cross Bridge in Dublin. Althought, the Portobello Plaza is still under construction, so for now a longer detour will be needed at one end.The otherwise one-way street, Windsor Terrace, has been marked by Dublin City Council to allow two-way cycling without any cycle lane or separated space. While the concept of contra-flow cycling without lanes can often seem daunting at first, this kind of provision is the norm on similar low-traffic, low-speed streets in cities in the Netherlands, France, Belgium, and other countries. While it might not be for everybody, it allows people who want to cycle two-way on the street to do so legally without having to take significant detours or make awkward manoeuvres on busy junctions. Windsor Terrace fits the bill for being low-traffic, low-speed, and with a short distance where the street is one-way before it opens out to areas where people cycling or driving can wait for somebody coming in the opposite direction where needed. Internationally, transport authorities and advocates note that allowing contra-flow cycling on such streets is simply legally facilitating what is already happening, and that would certainly be the case here. Dublin City Council has for decades provided such arrangements on a small number of streets, but up until recently, national guidance was lacking. As reported last November, guidance in the Traffic Signs Manual has been changed to allow contra-flow without separate or, indeed, any lanes.Current examples in Dublin include at Royal Canal Bank and Leinster Street North, both in Phibsborough; Hammabille Park, and Terenure Park, both in Terenure; and on Molesworth Street in the city centre. Most of these have operated for decades with little or no issues.
