Loop 288 is a state highway within the city limits of Denton, Texas. On the north side of town, the loop runs next to the C. H. Collins Athletic Complex. Despite its name, Loop 288 does not make a complete circuit, running instead around the north, east and southeast sides of the city. It begins at an interchange with I-35 on the northwest corner of Denton and loops around the north, east and southeast sides of the city before ending at another intersection with I-35E adjacent to Denton's shopping mall. The total length is 10.1 miles (16.3 km). In recent years, several large retail stores have been built on or near the southeast portion of the loop, and this, coupled with ongoing road expansion projects, has resulted in extreme traffic congestion.
Loop 288 is signed as a truck route for traffic traveling east on US 380 towards McKinney.
Loop 288 was designated on September 21, 1955 from US 77 north to US 380 (then SH 24). On June 9, 1966, Loop 288 extended westward to I-35W and northward and westward to I-35. On October 21, 1977, the section from I-35E to I-35W was cancelled. On May 29, 1991, another section of Loop 288 was added from FM 2181 to another point on Loop 288. The old route will become Spur 288 when the new route of Loop 288 is built. The proposed route will follow new construction from Spencer Road to Colorado Boulevard, Mayhill Road from Colorado Boulevard to I-35 and FM 2499, part of FM 2499 from I-35 to just south of Robinson Road, and new construction (right-of-way has already been acquired for this section) from just south of Robinson Road to FM 2181.
