Tesla CEO Elon Musk says that he would be willing to donate even more money as a way to accelerate the widening of a major north-south highway in Los Angeles, known as the 405 Freeway. So far, he’s already donated $50,000 out of a total cost that has now ballooned to $1.1 billion, but he said he’d gladly pay more to add more workers.

"[I’d pay more] as a contribution to the city and my own happiness,” Musk told the Los Angeles Times on Thursday. “If it can actually make a difference, I would gladly contribute funds and ideas. I've super had it."

On Wednesday, the city received the dubious honor of having the worst traffic in the country, according to data company Inrix.

The Times wrote that Musk says, “it's easier getting rockets into orbit than navigating his commute between [his] home in Bel-Air and his Space Exploration Technologies factory in Hawthorne,” a distance of less than 20 miles.

The primary contractor for the freeway widening project, Kiewit, has been instructed to keep the 405 open at all costs, and it defended its work in a statement sent to the Times on Wednesday. The project was originally slated to be finished by spring 2013, but it's looking increasingly likely that it won't be fully complete until the end of next year.

"The costs and schedule impacts are the result of the project's overall complexity and the significant challenges associated with multiple unexpected utility and right-of-way issues," the firm said. "Kiewit and [the Los Angeles County Metropolitan Transportation Authority] are committed to working together to minimize future delays and resolve final costs. We… are committed to delivering the highest-quality product on the I-405 project."
