Pennsylvania Route 143 (PA 143) is a 20-mile-long (32 km) state highway in Pennsylvania. It runs from PA 662 in Richmond Township, Berks County northeast to PA 309 near New Tripoli in Lehigh County. The route passes through rural areas, intersecting Interstate 78 (I-78)/U.S. Route 22 (US 22) in Lenhartsville, PA 737 near Kempton, and PA 863 in Lynnport. What is now PA 143 north of Lenhartsville was originally designated Legislative Route 285 in 1911. PA 143 was designated to in 1928 to run from PA 43 in Lenhartsville to PA 29 near New Tripoli. The route was extended slightly east through New Tripoli by 1940 following a realignment of PA 29. PA 143 was extended south to PA 662 in 1962.
PA 143 begins at an intersection with PA 662 in Richmond Township, Berks County, heading to the north on two-lane undivided Hard Hill Road. It turns northwest through a mix of hilly farms and woods with some homes, reaching the community of Virginville and becoming Main Street. In Virginville, the road crosses the Maiden Creek at the confluence with Sacony Creek into Perry Township, where it runs a short distance to the west of the Maiden Creek with woods to the east and farm fields to the west as an unnamed road. PA 143 continues through rural surroundings as it passes through Windsor Township and into Greenwich Township. The road enters more wooded surroundings and makes a few sharp turns prior to heading west into the borough of Lenhartsville. Here, the road becomes Chestnut Street and passes homes and businesses. The route intersects East Penn Street (Old Route 22) and heads west on East Penn Street for a short distance before turning north onto Willow Street.
Upon leaving Lenhartsville for Greenwich Township again, PA 143 becomes unnamed and reaches an interchange with I-78/US 22. From this point, the road winds north through more forested areas, still running to the west of Maiden Creek. The route enters Albany Township and enters a mix of woods and farms as it comes to an intersection with the northern terminus of PA 737 near the community of Kempton. Following this intersection, the road passes through more rural areas as it runs to the west of Ontelaunee Creek and the Wanamaker, Kempton and Southern Railroad.
PA 143 crosses into Lynn Township in Lehigh County, which is in the Lehigh Valley, continuing northeast to the community of Wanamakers as Kings Highway. At this point, the road turns more to the east and passes the terminus of the Wanamaker, Kempton and Southern Railroad as it heads into more agricultural areas with some homes. The route curves northeast and runs through the community of Jacksonville before it turns to the east. Upon reaching the community of Lynnport, PA 143 comes to the northern terminus of PA 863. From this intersection, the route continues farther east, curving southeast and crossing Ontelaunee Creek. PA 143 turns east and passes through New Tripoli as Decatur Street before reaching its northern terminus at PA 309.
In 2015, PA 143 had an annual average daily traffic count ranging from a high of 2,700 vehicles between PA 863 and PA 309 to a low of 1,000 vehicles between PA 662 and I-78/US 22. None of PA 143 is part of the National Highway System.
What is now PA 143 north of Lenhartsville was designated as part of Legislative Route 285, a legislative route that ran from Hamburg to New Tripoli, in 1911. PA 143 was designated in 1928 to follow its current alignment from PA 43 (now Old Route 22) in Lenhartsville northeast to PA 29 west of New Tripoli. The route was originally unpaved between Lenhartsville and Kempton while the section between Kempton and New Tripoli was paved. By 1940, PA 143 was paved between Lenhartsville and Kempton. Also by this time, PA 143 was extended through New Tripoli to end at PA 29 (now PA 309) to the east of the community following a realignment of PA 29. PA 143 was extended south from Lenhartsville to its current southern terminus at PA 662 on March 8, 1962.
