Keenesburg

An unsigned, state maintained Business Spur for I-76 begins at Exit 39 and follows Market Street north to County Road 18 and south to Old Highway 6 (I-76 Frontage Road) within the town of Keenesburg. Inventoried by CDOT as Route 076B, the spur is just 0.472 miles in length.

Fort Morgan, Brush and Sterling

This is the longest continuously signed Interstate business loop in the system. It follows U.S. 34 from Interstate 76 at Exit 75 through Fort Morgan and Brush east to Spur U.S. 34. Business Loop I-76 turns north on Spur U.S. 34, returning to I-76 at Exit 92. Turning northeast, Business Loop I-76 follows U.S. 6 from Exit 92 through Hillrose, Merino and Atwood into the Sterling city limits. Once in Sterling, the business route is signed as U.S. 6 primarily and with trailblazers “To Interstate 76.” The business route rejoins I-76 at Exit 125.

Prior to 2007, this business loop had 57 miles worth of continuous signage, including many new signs installed in 2003. After 2007, the majority of business loop signs were removed from within the city limits of Sterling but left intact in the other cities and towns through which it travels. Business Loop I-76 was signed concurrently with U.S. 34 from Fort Morgan to Brush and with U.S. 6 from Exit 92 northeast to Sterling. Over the years, signage has varied somewhat based on individual sign replacement projects. While some business route markers were removed in the 2000s, for instance, they reappeared in 2010 along U.S. 34 (Brush Spur Connection) south from Exit 92 to U.S. 34 west to the city of Brush.¹

Due to the fact that Business Loop I-76 overlaps portions of U.S. 34, Spur U.S. 34, and U.S. 6, the route is not inventoried in the CDOT Straight Line Diagram Tool.

Camden

I-76 Connector constitutes a 1.22 mile² long freeway spur linking I-76/676 at the Walt Whitman Bridge with U.S. 130 (Crescent Boulevard) and New Jersey Route 168 (Black Horse Pike) in Camden. There are no I-76C shields along this route, just signs directing travelers to I-76, I-676, the Walt Whitman Bridge and Philadelphia.

Moon Township and Findlay Township

Business Loop I-376 is a 6.88 mile long expressway along Airport Parkway through Moon and Findlay Townships. The business route skirts the eastern edge of Pittsburgh International Airport (PIT) as it winds northwest from Exit 57 to Exits 50-51.

The designation replaced Pennsylvania Route 60 Business on November 6, 2009, to coincide with the extension of Interstate 376 north to Beaver Falls. Signs for I-376 along sections of former I-279 (Penn Lincoln Parkway West), U.S. 22/30, and PA 60 started appearing as early as June 10, 2009. The final section of Interstate 376 to be signed was along the Pennsylvania Turnpike segment (James E. Ross Highway) by August 1, 2010.
