## Route description

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 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 a partial cloverleaf 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 west 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, and continues northeast to 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 Jacksonville before it turns to the east. Upon reaching Lynnport, PA 143 comes to a junction with the northern terminus of PA 863.

## History

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.

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 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.
