QuoteTransportation officials are delivering some early Christmas gifts this year, including this shiny bauble for south area drivers:
The 3-plus-mile, $95 million Cosumnes River Boulevard extension opens on Tuesday afternoon, offering a major, new east-west connector between Highway 99 and Interstate 5.
The road, which alternates between four and six lanes, connects from Franklin Road to Freeport Boulevard and includes a major interchange at Interstate 5 near the town of Freeport, just south of the Meadowview and Pocket areas of Sacramento.
The new thoroughfare gives south area commuters more options and will ease traffic congestion on Mack, Meadowview and several other south area roads, said Nader Kamal, the city's project manager.
For now, that is. But not necessarily for long.
That's because the new road and interchange also pave the way for construction of Delta Shores, a major shopping center and residential community — the biggest Sacramento has seen since the North Natomas area opened 15 years ago.
Preliminary work already is underway for a 900,000-square-foot commercial center on I-5. Merlone Geier Partners, a San Francisco-based developer, plans a Walmart, an R.C. Willey, a movie theater, a sporting goods store, a pet supply store, clothing stores, restaurants and assorted other retail outlets. Expect to see buildings sometime in 2016.
The city also has given approval for 5,200 homes along the boulevard, just south of the Meadowview community. Gary Muljat of Merlone Geier said his company will sell the land to home builders, but it does not have a definite timetable yet.
