State Route 261 (SR-261) is a 6-mile (9.7 km) state highway that connects Helena with Pelham in northern Shelby County, as part of the Birmingham/Hoover metropolitan area. SR-261 is two lanes wide for the entirety of its route. It serves as a feeder route to numerous subdivisions in Helena and Pelham.
The southern terminus of the route is at the intersection with Shelby County Road 17 (CR-17), CR-52, and CR-91 in Helena. The northern terminus is at the intersection with U.S. Highway 31 (US-31) in Pelham. North of US-31, the route is designated as CR-17 and continues to US-280 in the Inverness area of Hoover. Mileage is measured from Helena; miles are marked by roadside green metal mile markers. Throughout its length SR-261 is also known as and commonly appears on maps and street signs as Helena Road. The majority of the route is relatively level through suburban housing and commercial businesses, the steepest grades occur approaching and departing the Buck Creek floodplain.
It is expected that as work will begin to widen the highway to five lanes between US-31 and CR-105 (Bearden Road) as soon as 2012. Long range plans call for routing SR-261 around historic Old Town Helena via a new bypass that will intersect with CR-52 west of the current terminus.
SR-261 crosses the Vulcan Materials Helena quarry on a concrete deck bridge (MP 2.2) east of Old Town Helena. The route crosses Buck Creek on a concrete pier supported steel W-shape girder bridge with a concrete deck (MP 1.3). Steel railings provide vehicle protection, a narrow sidewalk is present on the downstream side of the bridge. SR-261 crosses three railroad tracks at grade consisting of the CSX Transportation Lineville Subdivision east of Buck Creek (MP 1.4) and the CSX Transportation S&NA Subdivision (and connected siding) west of Buck Creek (MP 1.2). The Lineville Subdivision crossing is equipped with flashing lights, the S&NA South Subdivision crossing is equipped with flashing lights and crossing arms.
