San Luis to begin overnight manhole repairs on Plaza Drive June 9

San Luis began overnight manhole rehabilitation along San Luis Plaza Drive on June 9, with work set for the 6 p.m. to 6 a.m. window that affects late-day drivers, deliveries and morning commuters. The city said traffic will be maintained in both directions throughout the project, with one northbound lane and one southbound lane open at all times.

Haydon Building Corp. is carrying out the repairs under traffic control measures that include partial lane closures. The City of San Luis said drivers should expect delays, reduce speed and stay alert for construction personnel and equipment in the work zone. Local traffic and business access will be maintained whenever safely possible, and residents and businesses inside the work area will continue to have access accommodations during construction.

The city also warned that the schedule could change because of weather, operational needs or unforeseen conditions, with the public to be informed if that happens. That makes the project part of the daily balancing act in San Luis, where even short-term street work can ripple through a border economy built around movement, access and commercial traffic.

San Luis was founded in 1930 with the opening of the international land border crossing and incorporated in 1979. The city says its economy is closely linked with San Luis Río Colorado, Sonora, across the border, and it describes itself as a border community where daily cross-border movement affects culture, language, heritage, environment and, most importantly, the economy.

The manhole repairs also come as San Luis manages a wider round of transportation and redevelopment work. The city and the Arizona Department of Transportation are reconstructing five miles of Cesar Chavez Boulevard between San Luis Plaza Drive and Avenue E, while the San Luis Port of Entry modernization represents a roughly $355 million investment that began construction in 2024. The city says 8 of 16 planned northbound lanes were operational in its latest update, with full operation expected by spring 2029.

Nearby, Phase II of the Merrill Avenue Improvement Project began May 18 and includes storm drains, manholes, sanitary sewer manholes and pavement replacement between County 22nd Street and Nancy Street. Taken together, the projects show a city tightening up its infrastructure while trying to keep traffic moving through a corridor where border commerce and neighborhood access depend on the same roads.
