Increased traffic at the intersection of North 7th Avenue and Griffin Drive is causing congestion and delays.
The primary goals of this project are:
- Reduce congestion.
- Reduce long-term maintenance costs.
- Improve bicycle and pedestrian mobility.

Reduce congestion by:
- Widening Griffin Drive and adding a left-turn lane at the intersection. This will create dual left-turn lanes heading south towards I-90.
- Widening Mandeville Lane to create an additional lane at the intersection.
- Widening North 7th Avenue to provide three northbound and southbound lanes at the intersection including left-turn lanes, and right-turn and through lanes.
Reduce maintenance by:
- Using concrete pavement instead of asphalt for most of the project. Concrete pavement is more durable and needs less maintenance than asphalt.
- Constructing a boulevard using stamped brick-red concrete rather than grass. Boulevard is the buffer between the sidewalk or bike path and the road (see graphic B-B below).
Improve bicycle and pedestrian mobility including:
- Modern pedestrian crosswalks including push buttons with audio for pedestrian crossing signal.
- Americans with Disabilities Act (ADA) compliant sidewalk ramps.
- Continuous 5-foot to 6-foot-wide sidewalk on both sides of North 7th Avenue and Mandeville Lane.
- Continuous 10-foot-wide shared-use path (for both pedestrians and bicyclists) along both sides of Griffin Drive.
- 4-foot to 6-foot-wide shoulders along North 7th Avenue.
- Safety railing on edge of the bike/pedestrian facility, where required.
The following are photos of the proposed roadway cross sections of the different legs of the intersection. The cross-section name (such as Section A-A) corresponds with the location and direction on the Overview Map above.
