After more than two years of planning, the City of Sonora is set to break ground next week on a $3 million project that will widen the northeast corner of Greenley Road and Mono Way.
City Engineer Jerry Fuccillo announced via email Friday that night-time utility relocation work is scheduled to begin Tuesday and will require lane closures that could lead to 10-minute traffic delays in the area of the intersection during work hours.
The first week of work is scheduled to run from 7 p.m. to 6 a.m. Tuesday through Friday. Fuccillo stated the schedule will be updated on a weekly basis, with an estimated completion date at the end of October.
Other aspects of the project will include grading, drainage, construction of sidewalks, changes to the signal system and paving improvements, Fuccillo stated.
George Reed Inc., based in Modesto, was awarded the $1 million contract for construction by the Sonora City Council at a meeting in late June.
Up to $2 million of the project’s total cost is being funded by Tuolumne County under an agreement approved by the Board of Supervisors in 2015. Both the city’s and county’s funds for the project come from traffic mitigation fees paid by developers over the years.
Much of the cost came from the need to purchase and demolish a former mini-mart and gas station at the northeast corner of the intersection.
In April, the council approved purchasing the business from owner Ken Keagy for $1.6 million to make room for the widening. Keagy was allowed to keep the fuel station canopy and car wash on the same corner as part of the deal, and he has said he plans to make improvements to it in the future.
This will be the second phase of improvements to the intersection that were originally approved by the council in January 2002. The first phase was completed in early 2003 and added a southbound lane to Greenley Road on the north side of the intersection.
One of the city’s goals has been to complete the second phase before the opening of Adventist Health Sonora’s Diana J. White Cancer Institute and Health Pavilion, which is anticipated for next year. The project is intended to improve traffic flow and safety at the intersection.
Adventist Health Sonora paid about $800,000 in traffic mitigation fees that helped fund the intersection work as part of its development agreement with the city for building the cancer institute.
The Board of Supervisors agreed to cover up to two-thirds of the cost because it’s one of the busiest intersections in the county.
