The District Department of Transportation says it is developing plans to improve three dozen intersections that it says pose a threat to pedestrians and cyclists.

DDOT said this week that it wants to make changes to 36 intersections with dual turn lanes. These intersections have been labeled “multiple risk” and have contributed to more crashes than typical intersections, the city said.

The changes are part of the city’s Vision Zero initiative, which seeks to eliminate transportation-related fatalities.

The District has already performed upgrades on four intersections and expects to begin work on nine others this summer. There are roughly 25 more that are undergoing analysis. Each intersection requires its own unique solution, but DDOT said some intersections will get signal phasing changes or dual turn lanes will be reduced to one.
