NDOT outlines non‑vertical traffic calming on Ewing Drive after commissioners lower speed limit
Summary
NDOT staff updated the Traffic & Parking Commission on measures around Ewing Drive after the commission authorized a reduced posted speed; staff said vertical measures are not eligible and described plans for non‑vertical traffic calming, signage and radar feedback while they evaluate longer-term options.
Nashville Department of Transportation staff updated the Traffic & Parking Commission on follow-up actions for Ewing Drive after the commission authorized a 35 mph posted speed for the corridor at a prior meeting.
Mister Smith told the commission NDOT has installed dynamic message boards to advise drivers of the upcoming speed change and has work orders in progress to replace signage and add radar feedback displays. He said the agency is evaluating non-vertical traffic-calming measures because Ewing Drive's traffic volumes and the current posted 35 mph speed render vertical measures (speed cushions/humps) ineligible.
"We are evaluating different traffic calming designs that do not involve vertical measures," Smith said, listing options that include flexible delineators to create a perceived lane narrowing, in-street pedestal signs and wider striping where resurfacing allows it. Smith said NDOT would share design results when they are finalized.
Public speakers raised ongoing speeding and truck traffic on Ewing Drive. Clarence Ewing Sr., a resident who identified himself as living on the corner of Ewing Lane and Ewing Drive, described vehicles traveling "about 65, 70 miles per hour" and urged additional measures. Another resident and Vision Zero advocate, Ben Hubert, asked the commission to add an agenda item to seek authorization for lowering the limit further to 30 mph and said he had a letter from the Vision 0 Advisory Committee supporting a lower speed on Ewing.
Staff clarified that Ewing runs along the border of multiple council districts and that previous steps included installation of an all-way stop at Ewing and Gwenwood and temporary signage. NDOT said it will report back with design options for non-vertical traffic calming and that any long-term changes to street classification or additional enforcement would involve coordination with other agencies and potentially the planning commission.
No formal vote occurred on new traffic-calming installations during the update; commissioners requested continued coordination and follow-up from NDOT.
