Bi-Directional Protected Lanes

Two-way bike lanes allow cycle movement in both directions, on one side of the road. Two-way lanes share some of the same design characteristics as one-way lanes, but may require additional considerations at driveway and side-street crossings. A two-way may be configured as a protected cycle track – at street level with a parking lane or other barrier – or as a raised cycle track to provide vertical separation from the adjacent motor vehicle lane. 

Bi-directional protected bike lanes are best suited for streets with long segments without access points, or where it is difficult for cyclists to cross the street. These include: one-way streets, parks, waterfront roads, wide boulevards and generally streets with fewer interruptions.

Bi-directional protected bike lanes have a standard minimum width of 2.5 meters, allowing for overtaking and riders in both directions. 

Bi-directional protected lanes separated from car traffic through physical barrier.
