When completed in the fall of 2012, the section of freeway in Anaheim will go from four lanes in each direction to five both eastbound and westbound from the 55 Freeway to the 241 Toll Road, one of the most backed-up highways in Orange County.
"Sections of this corridor, if you've noted, have been mentioned as being the second worst in the nation in congestion," said Corona Councilwoman Karen Spiegel.
Three-hundred-thousand commuters travel the 91 Freeway between the 55 and the 241 every day.
"The bottom line of this project is it gets people home to their families sooner," said Anaheim Mayor Tom Tait.
While the construction is expected to create about 900 jobs, it will also create more traffic in the area.
"Obviously it will contribute to some additional congestion for the time that the project is underway but it will be minimal," said Will Kempton, CEO of the Orange County Transportation Authority.
