The proposal for a single, reversible lane down the center evolved in the late 1980's.

Either a reversible lane or extra shoulder space is being considered for the additional lane.

Three lanes would be used for both directions, plus one reversible lane in the middle.

The expansion to four lanes in each direction at an expense of the reversible lane will also increase the average daily traffic by almost 60%.

It consists of a single reversible lane for automobiles and two bicycle lanes.

In certain situations, reversible lanes will be contraflow for a portion of the day.

At present, an informal car pool system called "slugging" has evolved around the reversible lanes.

On July 18, 2006 at 6 am, the reversible lanes opened to westbound morning traffic (only).

Many other questions were raised as a result of the low traffic volume along the reversible lanes.

The bridge has three reversible lanes, the use of which is indicated by signals.
