At the end of the bridge, the route comes to an interchange with PA 68 and heads west to form a concurrency with that route on Midland Beaver Road. The road passes through industrial areas as it crosses into Midland and becomes Midland Avenue, heading northwest through commercial areas with some homes. The two routes head through the commercial downtown of Midland and heads into residential areas.

Here, the route continues north to an intersection with PA 18/PA 108. At this point, PA 18 and PA 108 turn north to follow PA 168 on Moravia Street, passing more industry with some businesses. The road crosses two New Castle Industrial Railroad lines and becomes South Jefferson Street. PA 108 and PA 168 split from PA 18 by turning northeast onto four-lane undivided South Croton Avenue, passing between the Neshannock Creek to the northwest and industrial areas to the southeast. The road crosses US 422 Business and continues to an intersection with the northern terminus of PA 65. PA 108/PA 168 becomes North Croton Avenue and runs between the creek to the northwest and woods and homes to the southeast.

Northern terminus

The segment of PA 168 north of the Ohio River originally started north then turned eastbound in Ohioville to its northern terminus at PA 68 in Beaver. In 1936, this was changed to continue north past Ohioville, allowing PA 168 to extend up through New Castle/Lawrence County and to its new northern terminus at PA 208 in Leesburg/Mercer County. In 1959, nearby PA 278 was decommissioned and replaced as a realignment of PA 208; thus, PA 168 and PA 208 ran concurrent for the former's last three miles. By 1970, PA 168's northern terminus was truncated to its current location at the PA 208 junction in Volant/Lawrence County.

Ohio River crossings

From Hookstown northbound, PA 168 originally ran up Main and Hill Streets through Georgetown to Smith's Ferry which was used to cross the Ohio River to join the route's northern segment on Smith's Ferry Road in Ohioville. Both segments leading to the Ohio were later relocated. In 1946, the entire Smith's Ferry Road segment from the north was moved east onto Fairview Road and continued southbound onto Midland Avenue, forming a concurrency with PA 68 through Midland to Cooks Ferry in Industry. This left an uneven "gap" with the southern route until 1951 when PA 168 was moved out of Georgetown and rerouted along Pine Street in Hookstown to Cooks Ferry in Shippingport. Cooks Ferry provided the necessary PA 168 connection across the river between Shippingport and Industry until it was replaced with the Shippingport Bridge in 1964.
