Arbuckle

At a mere 1.1 miles long, Business Loop 5 in Arbuckle begins at Interstate 5 Exit 566, an interchange with no northbound re-entry. The route runs seamlessly north from the off-ramp to Fifth Street through downtown Arbuckle, then turns west onto Freeway Underpass Road to Exit 567, while Fifth Street continues north as Frontage Road ( Colusa CR 99W). Both interchanges are signed for "Frontage Road."


Williams and Maxwell

In Williams it begins at Interstate 5 Exit 575, runs north on Husted Road, and then northwest onto Frontage Road and Old Highway 99W, which runs along the west side of a former

. Within downtown Williams, the route takes a reverse curve away from the tracks into Seventh Street where it intersects California State Route 20 Business but then returns to its previous trajectory before running under a bridge for California State Route 20, which has one connecting road between the two routes on the northwest corner. North of Williams, the route passes through the unincorporated community of Cortena, where it shifts from northwest to north. Entering Maxwell the road makes another slight shift away from the former SP line, but not as far away as in Downtown Williams. It intersects Oak Street and Maxwell-Colusa Road (the main west–east road in Maxwell), and then shifts back to its previous trajectory at a mobile home park north of North Street. BL-5 continues along the west side of the tracks until ending at a half-diamond interchange with I-5 with only southbound off-ramp and northbound on-ramp at Exit 588. Old Highway 99W simply continues northward as Colusa CR 99W.


Willows and Orland

One of the longer business loops is the Business Loop 5 that runs between

line mentioned in Williams and Maxwell. The route follows the historic US highway past a bridge over a canal where it becomes South Tehama Street, and then North Tehama Street at the intersection with West and East Sycamore Avenues. At the intersection of West and East Wood Street (a.k.a.; Biggs-Willows Road) is California State Route 162, he first major intersection with the business route and the only one in Willows outside of its southern terminus. North of CA 162, the North Tehama Street name fades away as route makes a slight northeast curve where it crosses a railroad spur leading to a

Leaving Willows, BL 5 passes through farmland, interrupted briefly by communities like Bluegum, where it curves away from the tracks to run along Walker Creek, only to cross a bridge over that creek and resumes hugging the side of the tracks again. The next community is Artois, where it moves northwest further away from the old SP line than it was in Willows, but still turns back north again. Continuing its journey through rural

. Two blocks later, the road hugs the side of the tracks again, and the road runs under an arch at a short bridge over the Stony Creek Irrigation Canal immediately south of the intersection with Almond Way. The tracks curve to the northeast away from the route just before the bridge over Hambright Creek where the road enters Wyo and then runs over a longer bridge over Stony Creek After passing County Road 9 then County Road 8 on the east side, the business route turns left onto County Road 7, while the former US 99W continues northward as "Highway 99W."

Red Bluff

The long, Business Loop 5 in Red Bluff has historically been part of both

line until after the intersection with the driveway to Red Bluff Shopping Center where it curves to the northeast and crosses under a trestle for that line. The route maintains that northeastern trajectory until just before it crosses a bridge over Reeds Creek, where the name changes to Main Street. At Oak Street and Antelope Boulevard, BL-5 is joined by an overlap with California State Route 36. Two blocks north of there, northbound BL-5 and westbound CA 36 has an intersection with Walnut Street ( County Route A7) the road that leads to Shasta College. Less than three blocks later, the backyard of businesses along the east side is a bend in the Sacramento River, and BL-5 and CA 36 curve to the northeast just north of that bend at Dog Island Park. The routes run parallel to the former SP line again, but this time on the west side before approaching the intersection with Adobe Road. The northern terminus of CA 36 ends where that route heads west towards Fortuna, just before the bridge over Dibble Creek. The last intersection with both directions of BL-5 is with Hess Road just before the route approaches the flyover interchange with I-5 at Exit 651, which contains a southbound off-ramp and northbound on-ramp. The last intersection for northbound BL-5 is with Via Del Roble just before the aforementioned on-ramp with I-5.

along Dunsmuir Avenue at Exit 729 and Exit 732, but it also has an additional interchange at Exit 730, where it switches over from the east side of I-5 to the west side. Route Description
BL-5 begins at a trumpet interchange at Dunsmuir Avenue. The first sites along the road are a gas station and convenience store, two motels and a self-storage facility. The route winds through the mountains of the southern outskirts of the city, passing by the Dunsmuir Lodge motel. Between the intersection with Katherine Street and Hill Street it runs alongside the Dunsmuir Cemetery, officially entering the city limits halfway though. The route runs between Dunsmuir City Hall on the west side and Siskiyou County Sheriffs Office just before entering the Dunsmuir Historic Commercial District between Cedar and Spruce Streets. Exit 730 is a partial diamond interchange on the northbound side where the off and on-ramps don't connect to one another, and a southbound right-in/right-out interchange with a wide gap between the two ramps divided by the

along South Mount Shasta Boulevard at Exit 737 (mixed with California State Highway 89 at Exit 736) and North Mount Shasta Boulevard at Exit 740. Many of the businesses along the route are Alpine and Scandinavian mountain-themed motels. Route Description
Interstate Business Loop 5 begins at Exit 737 which has connecting ramps to and from Exit 736 ( California State Highway 89). The first intersection along the road is with South Mount Shasta Boulevard, a frontage road connecting to CA 89, which also connects southbound drivers to northbound I-5 via CA 89. North of that intersection the street name for the business route is South Mount Shasta Boulevard, with remnants of the old road on the northeast corner of that intersection. The road starts out as a two-lane forest road, though sparse development begins to show up after the intersection with Church Street where the road turns straight north. At the Evergreen Lodge, the route curves to the northwest, where development can now be found on both sides. Though primarily consisting of commercial development including motels and restaurants, a few residences can also be seen along the road. The northwest trajectory continue through the intersection with Old McCloud Road then turns straight north at Ream Avenue replacing the trajectory for that street. At a blinker light intersection with Mount Cloud Avenue and Chestnut Street, South Mount Shasta becomes North Mount Shasta and bends to the northwest again. The first intersection after this blinker light is West Lake Street (at City Hall) and East Lake Street, the former of which is County Road A10, a route that joins BL-95 for two blocks. The overlap ends at East Alma Street and CR A10 makes a right turn. It is here that the road runs parallel along the east side of a former

Shortly after passing by some industrial zoning, the remnant of an even older section of US 99 can be found at Ski Village Drive. After making a sharp curve to the west, the old section of US 99 is spotted again as Road Number 2M16, albeit cut off from BL 5 as a dead end street. The last intersection along the route is with Spring Hill Road, before BL-5 finally terminates at northbound I-5, while southbound BL-5 begins at a flyover interchange from Exit 740.
