NORTHERN CALIFORNIA – Work on a bridge project between Middletown and Calistoga is continuing despite an incident last week in which a construction crane toppled over.

The work on the summer construction phase of the Troutdale Creek bridge replacement project on Highway 29 in northwest Napa County began this month, as Lake County News has reported.

At around 11 a.m. Wednesday a large construction crane toppled over on the construction site, according to Vince Jacala, Caltrans public information officer for Napa and Solano counties.

Jacala said the crane's operator was not hurt.

The crew was able to upright the crane at around 10 p.m. Wednesday, Jacala said.

Caltrans' contractor on the project is Gordon N. Ball Inc. of Alamo. Jacala said Cal OSHA is investigating the accident.

Jacala said that, despite the incident, work was moving forward on schedule.

Caltrans has estimated that the project could be done late in 2016.
