Paving for the project to widen the intersection at Mono Way and Greenley Road will begin Nov. 5, marking the end of a three-year effort to repave the entirety of Mono Way within the city limits.

City Engineer Jerry Fuccillo said the city will also pave the stretch of Mono Way from the Greenley intersection to just short of Barretta Street near Grocery Outlet at a cost of $206,000.

The Greenley/Mono intersection construction cost $1.1 million. The county picked up two-thirds of the cost, the city the rest, from traffic mitigation fees paid by developers.

“This is basically the last project the city has that's on the traffic mitigation program,” Fuccillo said.

About $800,000 of the city's cost for the improvements came from fees paid for by Adventist Health Sonora, which is developing the Diana J. White Cancer Institute and Health Pavilion at the corner of Mono and Greenley.

Fuccillo said the project is coming in on time and within budget.

George Reed Inc. faced a few surprises including a pond about 3 feet underneath the gas station that was on the corner and a lot of large boulders that had to be extracted. Excavators bore holes in the rocks, filled the holes with water and used a shock device to break the rocks apart.

They also found the remains of a dump that included a lot of old medicine bottles and a rusty logger’s saw, Fuccillo said.

He said planners don't expect any problems for motorists turning right from the Greenley Road exit of the cancer center who want to then turn left fairly quickly onto Guzzi Lane. He said motorists would be crossing one traffic lane and then going into a left turn lane to Guzzi Lane.

He acknowledged that the traffic flow around the new cancer center was complicated by the right-turn only from the Mono Way entrance.

To create a traffic signal there, which would allow exits going both ways, it would have cost $300,000 to $400,000, paid for by Adventist Health, Fuccillo said.

This week, crews worked during the night to patch and seal cracks and to grind pavement to be ready to pave next week.

The paving will be a nighttime operation as well, from 7 p.m. to 7 a.m. Nov. 5 through Nov. 7. Fuccillo said 10-minute delays should be expected due to lane closures and diversions.

He recommended that drivers avoid the area entirely and use Highway 108 to Washington Street to get to downtown Sonora.

The $36 million cancer center is expected to be completed later this year and open in the spring.
