Passage: PA 42 begins at an intersection with PA 61 in the near ghost town of Centralia in Columbia County, which has been largely abandoned because of a mine fire. From PA 61, the route heads north on two-lane undivided Locust Avenue. The road passes through abandoned areas of the town which have been overgrown with trees. The route turns east and crosses into Conyngham Township, becoming South Main Street and heading into forested areas. PA 42 becomes a four-lane road and heads to the northwest, passing through the residential community of Aristes, where it narrows back to two lanes. The road curves to the northeast and becomes Numidia Drive, heading into the Weiser State Forest and turning to the northwest as it crosses Big Mountain. The route turns west and northwest through more dense forests, passing to the east of Shamokin Reservoir. Continuing to the west-northwest, PA 42 enters Locust Township as it crosses Little Mountain, leaving the state forest and turning to the north. The road heads into open agricultural areas with some woods and residences. The route briefly turns northwest before heading north again and passing through the community of Numidia. PA 42 curves to the northwest as it heads through more rural areas, crossing the Roaring Creek and continuing into Catawissa Township. The road runs through a mix of farmland and woodland with some homes, gaining a second northbound lane. The route becomes a four-lane road in a wooded area before turning into a three-lane road with one northbound lane and two southbound lanes. PA 42 comes to an intersection with PA 487, at which point that route joins PA 42 for a concurrency, with the two routes heading north through more woodland as a two-lane road. The road crosses the Catawissa Creek into Catawissa and becomes Mill Street, heading northwest into residential areas. PA 42 splits from PA 487 by heading west-northwest on Main Street, heading through the commercial downtown of Catawissa. The road crosses Norfolk Southern's Sunbury Line before heading across the Susquehanna River, at which point the road becomes Rupert Drive and heads into Montour Township. Here, the route turns north and crosses the North Shore Railroad. PA 42 runs through wooded areas immediately to the west of the railroad tracks with the Susquehanna River a short distance to the east. The road turns north-northwest away from the railroad tracks and heads through the residential community of Rupert. The route passes through more woodland with some homes before reaching an interchange with US 11.

Passage: Stalybridge is a town in the Metropolitan Borough of Tameside in Greater Manchester, England. It lies on the course of the River Tame and the Huddersfield canal, on undulating land in the foothills of the Pennines. Historically a part of Cheshire, it is east of Manchester city centre and northwest of Glossop. The road from Oldham, to the pennine passes: the Snake pass and Woodhead, bridges the river at this point. Stalybridge was the junction of three early railway companies. The Ashton, Stalybridge and Liverpool Junction Railway Company was formed on 19 July 1844 and the railway was connected to Stalybridge on 5 October 1846. On 9 July 1847 the company was acquired by the Lancashire and Yorkshire Railway. On 1 August 1849 the Manchester, Stockport and Leeds Railway connected Stalybridge to Huddersfield and later to Stockport. This line later became part of the London and North Western Railway.

Passage: The Battle of Callinicus () was fought in 171 BC between the Kingdom of Macedon and the Roman Republic near a hill called Callinicus, close to the Roman camp at Tripolis Larisaia, five kilometres north of Larissa, the capital of Thessaly. It was fought during the first year of the Third Macedonian War (171-168 BC). The Macedonians were led by their king, Perseus of Macedon, while the Roman force was led by the consul Publius Licinius Crassus. The Macedonians were supported by Cotys IV, the king of the Odrysian kingdom (the largest state in Thrace) and his forces, by Cretan mercenaries and by auxiliaries of mixed nationalities. The Romans had their Italian allies with them and were supported by soldiers provided by Eumenes II of Pergamon, as well as a force of Thessalian cavalry and Greek allies. The battle saw the deployment of troops with cavalry intermixed with light infantry. Although the battle was actually inconclusive because Perseus withdrew before it came to a conclusion, it was considered a Macedonian victory because the Romans suffered heavy casualties.
