Shared lanes (wide outside lane) are lanes that allow compatibility of operation for both motorized vehicles and bicycles. Since bicycles may be operated on all roadways except where prohibited by statute or regulations, shared lanes without markings already exist in many different urban, urban core, suburban and rural town settings.

Note that although marked shared lanes are allowed in the for certain conditions, TxDOT as a general policy does not recommend marked shared lanes for TxDOT roadways due to the higher speed nature of TxDOT roadways as compared to local jurisdictions.

Shared wide outside lanes in urbanized applications should only be used in locations with low volumes (3,000 ADT or lower) and low speeds (35 mph or less).

The usable width for a wide outside lane should be 14-ft maximum and 13-ft minimum. The usable width is measured from the lane stripe to either the gutter joint or 1-ft from the nominal face of a monolithic curb.

If the usable width is greater than 14-ft, a bike lane should be provided instead. Use of minimum travel lane widths may be necessary to incorporate the bike lane.

Typical supplemental signage may include: BICYCLES MAY USE FULL LANE (R4-11). Refer to the for signing applications.

Custom signage may include language instructing vehicles to change lanes to pass or use a 3-ft passing distance.

Not applicable as the roadway will be designed to accommodate motorist target design speeds which will exceed bicyclists.

Lighting can be a beneficial element for Shared Lane facilities. It can significantly enhance safety and visibility for cyclists, particularly at night or in low-light conditions. Effective intersection lighting should be prioritized when considering lighting as a part of this facility. It can assist all users to navigate the intersection safely and confidently, reducing the risk of conflicts.
