This continues previously completed upgrades along US 190 of two-lane to four-lane highways. The most recent of these improvements were made to the Heidenheimer area circa 2010.

(AASHTO) to move US 190 to a new bypass on the south side of Copperas Cove, leaving the original alignment to be made into a business route. The project had been in the planning phases since the 1980s. After delays due to the construction of what would become I-14 to the east of Copperas Cove, the $46.5 million bypass opened on January 29, 2015, and the original alignment became Business US 190. Business US 190's western terminus is located at a signaled intersection with US 190 and Farm to Market Road 2657 (FM 2657). Though signed east–west, the first section of the road runs north-to-northeast toward the city center of Copperas Cove. Turning east after, the road intersects FM 116, where FM 116 forms a short concurrency with Business US 190 for three blocks. After the concurrency, FM 116 breaks off and continues north towards downtown. Continuing eastward, the road intersects northbound FM 1113 and begins to enter the commercial district of Copperas Cove. The road continues due east past the town's center until it merges with I-14, US 190, and State Highway 9 (SH 9). There is no direct access from eastbound Business US 190 to westbound I-14/US 190 or SH 9.


Killeen

Business U.S. Highway 190-F is a 9.09 mile (14.6 km) long business route that runs through downtown Killeen that follows an old alignment of US 190. When US 190 was moved off the original route to a southern bypass around both Killeen and the town of Harker Heights in 1975, the remaining route was initially declared as State Loop 518. In an overhaul of state loop designations throughout Texas, however, the Texas Department of Transportation converted many former U.S. route and state highway alignments into business routes, thus creating Business U.S. Highway 190. Business US 190 begins at a

; the only access to the army base directly from US 190 Business is via Hood Road. The route continues east as Veterans Memorial Boulevard. It intersects State Highway 195 (Fort Hood Road) as the business route exits Fort Cavazos and enters Killeen city limits. The business route passes through downtown Killeen and crosses FM 439 once passing the commercial district. Continuing eastward, the route passes by Skylark Field Airport and enters Harker Heights, where it intersects both FM 3423 and FM 3219. Approaching US 190, the business route splits: according to the Texas Department of Transportation, the official west-to-east alignment of the route forks to Edwards Drive, while the east-to-west alignment continues on Veterans Memorial Boulevard, though both directions are signed as the business route on the boulevard. At either designation, the roads both lost the designation at their respective I-14/US 190 intersections.


Heidenheimer

Business U.S. Highway 190-J is a 2.5 mile (4.0 km) long business route that runs through the town of Heidenheimer along an old alignment of US 190. As US 190 has come to be a major thoroughfare through central Texas, traffic could not handle the two lane road in the primarily residential area. With houses on both sides of the road close to the roadway, a bypass was needed by the mid-2000s. A new four-lane bypass around Heidenheimer looped west around the town, opening in 2010. In October 2010, the AASHTO approved the movement of US 190 to the new bypass. Later in 2010, the Texas Department of Transportation requested AASHTO to also approve the new Business U.S. Highway 190, which had been signed by Texas since US 190's movement. The highway has been subsequently approved and the business route continues to be signed as such. Though more aligned north-to-south, the business route is signed west-to-east. It begins at a T-intersection with US 190 westbound. The entrance to Business US 190 is not accessible from the eastbound lanes of US 190 as a grass median divides the highway. Once on the business route, it turns almost immediately to the right and begins a southeasterly track towards the town of Heidenheimer. Another access road from US 190 allows eastbound traffic to turn onto the business route. This connector is signed as 'TO BUSINESS US 190' from the mainline road. Continuing eastward, the road intersects FM 93 at its eastern terminus, also allowing access to US 190. Entering the main residential part of the small town, the eastern terminus of FM 436 intersects Business US 190. Only slightly further east is Business US 190's eastern terminus, where traffic returns to US 190.

At this point, Scenic Highway is taken over by US 61, now heading north towards Natchez and US 190 continues westward towards Opelousas. Although US 61/190 Business has been signed as such since 1960, it did not formally get approval from the American Association of State Highway Officials (AASHO) until 1968.

The road begins at an intersection with US 190 to the west of downtown Covington. The business route continues eastbound into downtown Covington until it reaches Louisiana Highway 21 (LA 21). From here, LA 21 begins to run concurrently with US 190 Business until it returns to US 190 on the east side of Covington. The route was approved by AASHO in June 1969, along with the US 190 rerouting.

After increased traffic on Gause Road and motorist confusion accessing US 190, the state of Louisiana petitioned AASHO to re-route the highway and create a new business route. At AASHO's June 1971 meeting, this request was approved. US 190 was permanently routed onto the now widened Gause Boulevard and Military Road while US 190 Business was signed along the former routing by 1975. Following
