The road’s closure, which is the major connector between Interstate 5 and State Route 45, will be in effect at least 10 days while major repairs are being made.
Officials said the failure of the culvert, located between Four Mile Road and Holloway Road, caused the westbound lane to subside under the weight of traffic and that the repairs needed are beyond the technical capacity and equipment abilities of the Colusa County Road Department.
“We recognize that this is a significant arterial road closure, and we appreciate patience and understanding as we work to address the damage,” said Public Works Director Michael A. Azevedo in a statement on Tuesday.
The Colusa County Board of Supervisors held an emergency meeting on Wednesday and approved the approximate $130,000 expenditure from the county’s road fund to contract with George Reed Inc. to do the repairs.
The action required a four-fifths approval to have the work contracted without going out to bid.
The repair was deemed urgent after the road subsided 1.5 feet over the course of just 48 hours, beginning on March 19, officials said.
Motorists who routinely travel the Maxwell Road (also known as Maxwell Colusa Road) are asked to avoid the closure in their daily transit activities for the next 10 days.
Motorists can access Interstate 5 from Colusa by traveling west on Highway 20 to Williams. To access Interstate 5 in Glenn County, motorists can travel north on State Route 45 to Norman Road, in Princeton.
