Long-term closure of South Duke Street for infrastructure improvements
WHAT: Long-term closure of South Duke Street for infrastructure improvements
WHEN: Beginning Monday, Jan. 5, 2026
Closure expected to be lifted March 31, 2026
WHERE: South Duke Street between Dauphin Street and Chesapeake Street
DETAILS: The city of Lancaster will implement a long-term closure of South Duke Street to allow crews to complete stormwater separation pipe installation, utility structure installation and temporary paving restorations.
Southbound traffic will be detoured via Church Street, South Lime Street, East King Street and South Broad/Chesapeake Street. Northbound traffic will be detoured via Chesapeake Street, South Queen Street and Church Street.
Local traffic will be permitted in portions of the closed area; however, through traffic will not be allowed. Motorists should follow posted detour signs and informational project signage.
This work is part of a larger South Duke Street improvement project that includes curb and sidewalk reconstruction, ADA-compliant ramps, a shared-use pathway, highway lighting, traffic signal upgrades, paving, signing, pavement markings, green infrastructure and stormwater separation. Completion of the overall project is anticipated in summer 2026.
