## E2

County Route E2 (CR E2) is a county highway in Sacramento and Placer counties in the U.S. state of California. It is a major north–south arterial thoroughfare running from State Route 99 in Elk Grove to Interstate 80 in Roseville. The route is known as Grant Line Road, Sunrise Boulevard, Sunrise Avenue and a small portion of Douglas Boulevard.
The Grant Line Road portion of the route is part of the Capital SouthEast Connector project, a planned 34-mile (55 km) expressway that will run from Interstate 5 at the Hood-Franklin Road interchange just south of Elk Grove to US 50 at the White Rock Road / Silva Valley Parkway interchange in El Dorado Hills. The CR E2 portion between SR 99 and Bradshaw Road have already been upgraded, while the portion between Bradshaw and Sunrise Boulevard remains a two-lane roadway and are in the planning stages of being upgraded.

### Route description

County Route E2 begins as Grant Line Road at the interchange with State Route 99. It heads northeast on a four to six-lane roadway, reducing to a rural two-lane roadway just past Bradshaw Road, skirting the city limits of Elk Grove to the west. The route then turns north onto Sunrise Boulevard, where it remains a two-lane roadway, intersecting State Route 16 (also known as Jackson Road). CR E2 enters the city of Rancho Cordova and dramatically widens to five lanes near the intersection of Kiefer Boulevard. This stretch of roadway was widened between Kiefer Boulevard and Douglas Road to accommodate increasing traffic to the surrounding housing development. After CR E2 gains a sixth lane, the route turns northwest just after Douglas Road and then turns north again approaching White Rock Road. It approaches U.S. Route 50 at an interchange, then skirting the community of Gold River to the east. The route leaves Rancho Cordova, crossing the American River and into the community of Fair Oaks. It enters the city of Citrus Heights after Madison Avenue and into the Sunrise MarketPlace, the city's shopping district. After passing Sunrise Mall and its intersection with Greenback Lane (County Route E14), the route is reduced to four lanes. It remains four lanes for the remainder of the route, passing Antelope Road, and entering Placer County and the city of Roseville. The route becomes Sunrise Avenue at the county line for a few miles, turning west on Douglas Boulevard and ending immediately at I-80.

CR E12 was first established in 1971 when the area was just a small farming community, and the segment of I-5 through the region between Stockton and Sacramento was not completed until 1979. The area has since experienced significant urban development, and Elk Grove was later incorporated as a city in 2000. East of Elk Grove Florin Road, CR E12/Elk Grove Boulevard narrows to two lanes and proceeds east through the historical "Old Town" section of Elk Grove to its terminus with Grant Line Road (CR E2).

## E14

County Route E14 (CR E14) is a county highway in Sacramento County, California, United States. It runs from State Route 99 in Sacramento to Hazel Avenue (County Route E3) in Orangevale. Known as Elkhorn Boulevard and Greenback Lane, it is a major east–west arterial thoroughfare that connects the cities and communities of Sacramento, Rio Linda, North Highlands, Foothill Farms, Citrus Heights, and Orangevale.

### Route description

County Route E14 begins on Elkhorn Boulevard at the interchange with State Route 99 north of Sacramento. It starts out as a two-lane roadway, skirting the northern end of the North Natomas development of Sacramento. As it enters the rural community of Rio Linda, the roadway expands to four lanes and remains at least four lanes throughout the remainder of the route. The landscape changes from rural to suburb as it passes through North Highlands and Foothill Farms, where the roadway expands to six lanes at Don Julio Boulevard. As it reaches the interchange with Interstate 80, the route becomes Greenback Lane. Shortly thereafter, it enters the city of Citrus Heights and remains in the city for 3.5 miles (5.6 km). As CR E14 reaches Sunrise Boulevard (CR E2), it enters the city's shopping district, Sunrise MarketPlace, and passes by Sunrise Mall. As it exits Citrus Heights and into the community of Fair Oaks, the roadway is reduced to four lanes as it reaches its terminus at Hazel Avenue (County Route E3) in Orangevale. The roadway itself continues as Greenback Lane towards the city of Folsom.
Elkhorn Boulevard west of SR 99 (without the county route designation) continues west to the Sacramento International Airport, passing through the Metro Air Park industrial complex. Elkhorn used to end at Power Line Road but was extended into the airport as an alternate route as Interstate 5 is the main route to the airport. The extension officially opened on May 21, 2024. A separate Elkhorn Boulevard is west of the airport but is a rural and narrow country road that is inaccessible to the airport. It runs from Garden Highway to a closed gate just short of the airport's property border.
The name "greenback" refers to the use of paper money for financial transactions at a time when gold and silver coin was the preferred rate of exchange. The property that Greenback Lane lies on was bought with greenback dollars (United States Note). The owner is said to have wished to be paid with coin, and became angered when he was not, hence the name "Greenback Lane."
   Greenback Lane has a very interesting origin. Previous to 1873, the inhabitants of Haggin Grant District had only the narrow, stony trails leading through the dense timberlands to serve as outlets from their homesteads. The discomfort and disadvantages wrought by these crude by-ways impelled the farmers to demand a main road. A county survey determined the amount of land necessary to grant the demand of the land holders. In settling with Mr. Cornelius Donohue, a large land owner, for the road land, a dispute arose as to the medium of exchange. Mr. Donahue insisted that his portion of the land be paid for in "greenbacks", for it was neither safe nor convenient to carry a large sum of coin in those days. It was no easy matter for the county to secure such a large number of greenbacks; nevertheless, they were still requested. After months of discussion, Mr. Donahue won his point, and the land was paid for in greenback notes. From this incident, the highway has been named "Greenback Lane."
Construction to expand Greenback Lane between Dewey Drive / Van Maren Lane and Auburn Boulevard in Citrus Heights from four to six lanes was completed in 2008, creating an entirely six lane thoroughfare within the city of Citrus Heights.
