Lane reversals


A lane reversal is an arrangement where traffic is permitted to flow in different directions during different times of the day. It is generally used to provide additional capacity for peak period traffic flow. The lane reversals are in effect Monday to Friday excluding holidays. There are some exceptions to the holiday exclusions.

overhead traffic lights on lane reversal
Overhead displays indicate the direction of travel for a reversible lane.  A green arrow identifies a lane as being open while a red X identifies a lane that is closed. 


The overhead signal display is set to provide advance warning about the opening or closing of the lane reversal traffic pattern with a flashing red X indicating that a lane is about to close.


temporary lane reversal signAt some locations, a manual lane reversal system may be deployed.  Temporary signage and traffic pylons are used to indicate the correct lane usage, then manually  altered at different times of day. These manual deployments are often used to decrease congestion near construction sites, or to test candidate locations for a permanent lane reversal system.

There is a High Occupancy Vehicle lane that operates on Centre Street in conjunction with the lane reversal. This lane gives priority to vehicles carrying two or more people. Additional information on the HOV lane can be found on the HOV lane web page.
