Columbus Blvd South of Grant Closure
Published on July 09, 2025
On Monday, July 14, 2025, at approximately midnight, crews are scheduled to close Columbus Boulevard south of Grant Road in preparation for several months of extensive underground utility work.
Through October 2025, travel restrictions will be in place at this intersection. Crews will be adding new water lines, new sewer lines and underground storm drain improvements in this area that require deep excavation across Columbus Boulevard.
Also, on Monday July 14, between midnight at 6 a.m., traffic on Grant Road between Sparkman Boulevard and Alvernon Way will be shifted from the north side of the roadway onto the newly paved south side of the roadway to allow crews to conduct work on the north side. Left turns will be prohibited, business access will be maintained.
This schedule is subject to change due to inclement weather or unforeseen circumstances.
The Grant Road Improvement Project from Sparkman Boulevard to Swan Road started in late May 2024. At completion, this improvement project will include six travel lanes, landscaped medians, buffered bike lanes, sidewalks, transit stop upgrades, indirect left turns and protected intersection improvements at Alvernon Way and Grant Road. A 96-inch diameter underground storm drain system will also be constructed throughout the project limits. This project is expected to be complete by the end of 2026.
The Regional Transportation Authority, a political subdivision of the state and independently governed, has invested more than $1.4 billion in transportation projects and services to improve mobility, safety, economic vitality and quality of life in the region. The RTA collects a half-cent excise (sales) tax from its special taxing district within Pima County to fund its 20-year regional transportation plan. The plan and tax were approved by voters in May 2006. The Grant Road Phase 3&4 Improvement Project is part of the RTA plan and is managed by the City of Tucson.
