15th Street Bikeway

As Denver continues to grow so does the demand on the transportation network. The 15th Street Bikeway demonstrates Denver Public Works’ promise to provide for and encourage use of all modes of travel. The 15th Street Bikeway provides a vital bicycle connection in Denver’s bicycle network. Using the bikeway, bicyclists can now easily access the Cherry Creek trail or lower downtown by continuing along the right side of 15th Street after the bikeway ends.

The new left-side bike lane on 15th Street between Cleveland Place and Larimer Street was installed in summer of 2013. The new bikeway helps organize all modes of traffic along the corridor, with bicyclists using the left lane, motorists in the middle lanes, and buses on the right.

The new features along 15th Street include:

Bike Box –
A green bike box was installed at 15th and Cleveland to increase the visibility of cyclists at the intersection. In the bike box, cyclists take their position ahead of cars, to gain priority to move into the intersection when the signal turns green. Drivers must stop behind the green bike box at the white stop line. Both bicyclists and motorists must wait for the traffic signal to turn green, and when it does, they may move through the intersection with caution, with bicycles in the bike box traveling first to enter the left-side bikeway.
 
Left Side Buffered Bike Lane –
A designated bike lane on the left side of the roadway is bordered on the right side with a sienna-colored buffer that clearly delineates the bike lane from the travel lane from Cleveland to Larimer.
 
Mixing Zone –
Mixing zones are the areas where motorists making left turns and cyclists continuing through the bikeway will merge before the intersection. In the five mixing zones along the corridor, motorists must yield to bicyclists before entering into the mixing zone to make a left turn. Motorists approaching mixing zones are encouraged to LOOK LEFT before entering the shared space.
 
Green Pavement Markings –
Green pavement markings increase awareness to the presence of bicyclists, particularly in areas of potential turning movement conflicts. Green pavement markings define where a vehicle and bicycle share space, such as at a mixing zone or intersection. The markings also provides guidance to bicyclists on where to position themselves across the intersection.
 
Turn Queue Boxes –
Green Turn Queue Boxes help cyclists turn right from the left-side bike lane. The turn queue box positions cyclists ahead of the crosswalk of the intersecting street, facing the intended direction of travel. The cyclist waits for the signal to turn green and then proceeds through the intersection on the right hand side.  Turn queue boxes exist at Welton and Lawrence.
 
Bicycle Signal –
At the intersection of 15th and Lawrence, Public Works has included a bicycle traffic signal. This provides bicycles their own phase to move across the intersection, allowing the diagonal movement to the right-side of the street for bicyclists continuing to travel to lower Downtown.
