The town, situated on the south bank of the Yadkin River, lies beneath Daniel Boone's hunting trails through the Brushy Mountains, in the foothills of the Blue Ridge Mountains. Visitors are served by a state-of-the-art Welcome Center. With retail and specialty shops/services in the immediate area, Jonesville offers an expanding antique mall at exit 83. Within five miles are regional sky diving facilities, an international motorcycle manufacturing plant, a restoration center for vintage cars, a popular herb farm, a History Center and historic park, a medieval reenactment center and a horse ranch specializing in riding lessons and mustang rehabilitation.

Seven local hotels, multiple fast food and conventional restaurants and gas stations are located near I-77 exits (83 and 79). Jonesville offers convenient access to athletic, college, cultural and recreational resources in larger Piedmont cities such as Winston-Salem, Statesville and Charlotte.

A military out-post during the Revolutionary and Civil Wars, Jonesville is not a typical "Interstate town." Currently working to preserve its history, it is home to an historic Bicentennial Park (Mineral Springs Park) featuring a Tri-County Veterans' Memorial with 3,000+ names of those who have served our nation since pre-Revolutionary War conflicts. The Mineral Springs Park, located along the Yadkin River, was once a respite where multiple wilderness trails converged, approximating highways 67 and 21 through Yadkin County. A recreational park (Swaim Park) with playgrounds, ball fields, tennis courts, walking trails, picnic areas and bandstand adjoin a Senior Center and a Medical Center.

A GreenWay along the Yadkin River is under development. Future plans include reconstructing a functional ferry that operated during the Civil War and establishing a walking trail along the historic woodland routes that converged in historic Mineral Springs Park.

The Yadkin River divides Jonesville and Elkin. The area is referred to as the Tri-County (Surry, Wilkes, Yadkin) Region and is located in the Yadkin Valley AVA, an American Viticultural Area. Wines made from grapes grown in the Yadkin Valley AVA may use the appellation Yadkin Valley on their labels. At least a dozen wineries are located within 15 miles (24 km) of the town.

According to the United States Census Bureau, the town has a total area of 1.9 square miles (4.9 km), of which 1.9 square miles (4.9 km) is land and 0.04 square miles (0.10 km) (1.05%) is water.

Interstate 77 runs through the east of town. The town is accessible via two interstate exits: North Carolina Highway 67/Winston Road and Business U.S. Route 21 in the Arlington area. N.C. 67 is a heavily used artery, linking Jonesville with Winston-Salem.

Until recently, two bridges linked the commercial districts of Jonesville and Elkin, the Hugh G. Chatham Bridge and the newer Gwen McNeill Bridge, less than a mile upstream on Business U.S. 21. The Chatham Bridge, built in 1931 and regarded by many in the area as a community symbol with its tall steel beams, was closed in November 2005 after it failed a state inspection. The North Carolina Department of Transportation does not plan to reopen or replace the bridge. Neither city would take the risk of insuring the bridge so it could be saved as a historic landmark.

Swan Creek Airport, which is privately owned, is southwest of town and is the home of the Carolina Sky Diving School. Elkin Municipal Airport is located in nearby Elkin. Commercial flights are available through Piedmont Triad International Airport in Greensboro and Charlotte Douglas International Airport.

Jonesville is Yadkin County's oldest town and was at one time the largest town west of Raleigh, according to An Illustrated History of Yadkin County 1950-1980, by William E. Rutledge Jr. Initially called Allen's Settlement, after the owner of an early iron ore forge, the settlement was established behind a towering, protective bluff above the south bank of the Yadkin River. It soon became a commercial hub for the region, featuring a trading post, a tannery, medical personnel, a school, grist and lumber mills, a cotton mill and a garrison overlooking the Yadkin Valley that served as an outpost for local militia during the Revolutionary and Civil Wars. Although a contemporary designation aligns the overmountain trail-head in an adjoining Surry County community, Allen's Settlement—formerly located in Surry County—is now recognized as part of the OverMountain Trail. Based on family journals and oral history, Allen's Settlement and historic Mineral Springs Park are identified as a mustering site for patriots who marched to defeat the British at Kings Mountain.

Allen's Settlement was incorporated as Martinsborough in 1811, but the name was later changed to Jonesville in honor of Hardy Jones (1747–1819). Jones fought in the American Revolution and was instrumental in bringing the Jonesville Male and Female Academy to Jonesville. A marker to Hardy Jones is on the lawn of Jonesville United Methodist Church.

In addition to the timber and iron ore markets, the town also grew around the Jonesville Male and Female Academy, according to Rutledge. The Academy was affiliated with the North Carolina Conference of the Methodist Church. The Rev. William L. Van Eaton, who was born in Davie County, was principal of the school at its peak in 1859. In its history, the Academy attracted numerous scholars of the era, including Bishop Francis Asbury and Brantley York, subsequent founder of Trinity-Union Institute, which was later named Duke University.

On April 1, 1865, troops commanded by Union Brigadier General George Stoneman and Colonel Alvan C. Gillem devastated the town and the Academy in their search for Confederate soldiers and supplies. In the Academy, they broke chandeliers and destroyed school equipment. This marked the end of the school.

Gillem's troops, known as "home Yankees," also ransacked businesses and chased away teachers and military-aged men. Union troops had been told the town was a haven for Confederate spies and military supplies. They failed to find evidence of an Underground Railroad for escaping slaves and deserting soldiers, assumed to be located in private homes and the iron ore caves in Jonesville. The town never fully recovered.

One of the last pieces of early town history, a house once occupied by Van Eaton that dated back to the 1830s, was torn down in 1996. At the time, it was believed to be the oldest house in town.

On December 21, 1912, two elderly women and a young girl were killed and nearly 100 people were injured after the floor of the Jonesville High School auditorium collapsed during a Christmas concert. As the floor of the second-floor auditorium gave way in the center, the audience of at least 300 people dropped to the first floor. Killed were: Nancy Swaim, Mrs. William Smith and Lexie Luffman, a 12-year-old girl. Sam Ray extinguished a fire in a stove in the auditorium as the floor began to collapse, saving many lives (Winston-Salem Journal).

The town experienced unprecedented growth after Interstate 77 opened in 1974. The intersection of Interstate 77 and N.C. 67 (Winston Road) on the east side of town is a popular stop for travelers. It is one of the most developed along the interstate between Statesville and Mount Airy.

In 1980, Jonesville was named a "Governor's Community of Excellence" by Governor Jim Hunt for its economic development work.

Jonesville Police Sgt. Gregory Keith Martin was shot to death on October 5, 1996, on I-77. The case, which has been solved, received national attention on TV's America's Most Wanted in May 2005, January 2006 and June 2006. Martin was the town's first police officer to be shot in the line of duty. On October 3, 2012, 36-year-old Scott Vincent Sica was arrested in Cape Coral, Florida, and charged with first-degree murder. In 2009 The town put up a memorial to Sgt. Martin in front of the new town Hall. Every year there is a memorial ride through Jonesville to honor Sgt. Martin.

In 2009, the town built a multimillion-dollar town hall.

Two community newspapers, The Tribune in Elkin and its sister paper The Yadkin Ripple, provide coverage of Jonesville. The Winston-Salem Journal, a larger daily newspaper, also covers the town.

Jonesville is part of the Piedmont Triad radio and television market, but many broadcasts from the Charlotte and Winston-Salem markets can be received as well. The cable provider is Time Warner.
