Interstate 505 North


Interstate 505 north
Interstate 80 east and Interstate 505 north split at Exit 56, and a secondary ramp as part of this interchange connects northbound Interstate 505 to Orange Drive in the city of Vacaville. Use Orange Drive to the Factory Stores at Vacaville, Orange Tree Plaza, Leisure Town, and Nut Tree Road south. The city of Vacaville was incorporated in 1892 and home to 88,642 people as of the 2000 Census. Vacaville sits at an elevation ranging between 90 and 300 feet. Average annual rainfall is 17.39 inches, and temperatures range from an average of 94 degrees during the day in summer to 36 degrees during winter nights. Photo taken 03/31/05.
The first exit along northbound Interstate 505 is Exit 1, Vaca Valley Parkway. Vaca Valley Parkway travels east to Interstate 80 at Exit 57 (Leisure Town Road) and west to Browns Valley Road. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 1, Vaca Valley Parkway. Photo taken 03/31/05.

This mileage sign along northbound Interstate 505 provides the distance to Winters (11 miles) and Redding (160 miles north via Interstate 5). This sign is posted at the Vaca Valley Parkway overpass. Photo taken 03/31/05.
The first reassurance shield on Interstate 505 north is posted after the Vaca Valley Parkway on-ramp. Photo taken 03/31/05.

The next exit along Interstate 505 north is Exit 6, Allendale Road. This interchange serves the unincorporated community of Allendale. Interstate 505 in Solano County generally retains two concrete lanes in each direction; the reflective signs were likely installed around 2000 or 2001, before the exit numbering directive was implemented. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 6, Allendale Road. Photo taken 03/31/05.
This Interstate 505 north reassurance shield is posted after the on-ramp from Allendale Road. Most of Interstate 505 passes through ranching and farming areas, with limited development until passing by Winters. Photo taken 03/31/05.
The next exit along Interstate 505 north is Exit 10, Putah Creek Road. This exit also connects to Gaddini Road. Photo taken 03/31/05.
The main exit to the city of Winters from Interstate 505 is at Exit 11, California 128/Grant Avenue west and Yolo County E-6/Russell Boulevard east. Use Exit 11 to historic downtown Winters via California 128. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 10, Putah Creek Road and Gaddini Road. Photo taken 03/31/05.
The next exit along Interstate 505 north is Exit 11, California 128/Grant Avenue west to Winters, Lake Berryessa, Napa Valley, Calistoga, and Cloverdale. To the east, Yolo County E-6 follows Russell Boulevard east toward the city of Davis and California 113. This interchange serves as the eastern terminus of California 128. Photo taken 03/31/05.
Prior to Exit 11, Interstate 505 crosses Putah Creek, leaves Solano County and enters Yolo County. At this point, Interstate 505 skirts the edge of the city of Winters. The population was 6,125 people as of the 2000 Census, sits at an elevation of 131 feet, and consists of 2.8 square miles in area. In Yolo County (from Putah Creek north to Exit 24/Road 19), much of Interstate 505 was constructed in 1959 as a two-lane expressway/freeway, and in 1980, additional interchanges were added and the freeway was widened to its current four-lane configuration. Photo taken 03/31/05.
Northbound Interstate 505 north reaches Exit 11, California 128/Grant Avenue west to Winters, Lake Berryessa, Napa Valley, Calistoga, and Cloverdale. To the east, Yolo County E-6 follows Russell Boulevard east toward the city of Davis and California 113. Plans originally called for California 128 to continue east to Davis, but that extension has not been constructed. Yolo County E-6 currently serves in that capacity. After this interchange, Interstate 505 will leave the city of Winters and enter unincorporated Yolo County. Photo taken 03/31/05.
The California 128 overpass was built in 1959 as part of Interstate 5W. This partial cloverleaf interchange is among the oldest structures on Interstate 505. The concrete bridge railing betrays the age of the bridge, yet it is neat to see it still in place. Photo taken 03/31/05.
After the California 128 interchange, this Interstate 505 reassurance shield is posted. Photo taken 03/31/05.
This mileage sign provides the distance to Williams (46 miles) and Redding (150 miles). Both cities are located along Interstate 5, well north of the merge point between Interstate 505 and Interstate 5. Photo taken 03/31/05.
The next exit along Interstate 505 north is Exit 15, Road 29A. Like Tulare County, most rural roads in Yolo County are given numerical designations that are separate from the county numbering system used throughout the state. Road 29A is approximately 29 miles from the northern border of Yolo County, but that is not always a precise measurement. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 15, Road 29A. This exit serves local farms and ranches. Photo taken 03/31/05.

Photo taken 03/31/05.
Use California 16 west to the unincorporated community of Madison. The old alignment of Interstate 505' predecessor county road is Road 89, which faithfully follows Interstate 505 between Winters and Madison on the west side of the freeway. Photo taken 03/31/05.

This mileage sign again provides the distance to Williams and Redding. To the east of the freeway, the western half of the Path 15 500kV power lines come into view. They will parallel Interstate 505 for the next several miles. Photo taken 03/31/05.
An Interstate 505 reassurance shield is posted after the on-ramp from California 16. After this sign, Interstate 505 crosses Cache Creek, which is the only outlet from Clear Lake southeast into the Sacramento River system. Photo taken 03/31/05.
The next exit along northbound Interstate 505 is Exit 24, Road 19. Photo taken 03/31/05.
Two sets of 230kV power lines aim to the northwest; they will parallel the Path 66 500kV power line toward Redding. Meanwhile, the western half of the Path 15 500kV power lines (Pacific Gas and Electric) turns northeast toward Zamora and the Sutter Buttes. The western and eastern branches of Path 15' 500kV system will reunite northeast of the Sutter Buttes at a point northwest of Yuba City. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 24, Road 19. The Path 66 Western Area Power Administration (WAPA) 500kV power lines, which are notable for their distinct shape when compared to Pacific Gas and Electric' Path 15 500kV power line towers, cross over Interstate 505 at this exit. From this point north to Interstate 5 near Dunnigan, Interstate 505 was built in 1977. Photo taken 03/31/05.
The next exit along Interstate 505 north is Exit 28, Yolo County E-10/Road 14 east to Zamora and Knights Landing. Photo taken 03/31/05.
Leaving the agricultural flat areas and entering the Dunnigan Hills, Interstate 505 passes through rolling green hills during this early spring photo. During summer, these hills change to a golden brown hue as the seasonal grasses dry out. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 28, Yolo County E-10/Road 14 east to Zamora and Knights Landing. Photo taken 03/31/05.

The distant Sutter Buttes come into view faintly as Interstate 505 approaches its next exit at Exit 31, Road 12A. Photo taken 03/31/05.
Northbound Interstate 505 reaches Exit 31, Road 12A. This is the final standalone interchange along Interstate 505 north. Photo taken 03/31/05.
The next two exits serve the unincorporated community of Dunnigan. Interstate 505 will merge onto Interstate 5 north, and the first interchange on Interstate 5 (Exit 554 to Road 8) connects to Dunnigan. Photo taken 03/31/05.
A standalone "Junction North Interstate 5" trailblazer is posted prior to the merge point where Interstate 5 and Interstate 505 come together. It would be helpful if this sign were accompanied by an Interstate 505 ends shield assembly. The Interstate 5/505 separation structure was built in 1968, well before the Interstate 505 freeway was completed in 1977 and 1980. Photo taken 03/31/05.
After Interstate 505 crosses over Interstate 5, the northbound lanes swing wide around the freeway to allow for a fast connection onto Interstate 5 north. Photo taken 03/31/05.
As traffic from Interstate 505 merges onto Interstate 5 north, the two northbound lanes merge into one and become the exit only lane for Road 8, which is Exit 554. Merge left to follow Interstate 5 north to Arbuckle, Williams, Maxwell, Willows, Orland, Corning, Red Bluff, and Redding. Photo taken 03/31/05.
