troops then launched a successful surprise attack on
Hessian troops at the
Battle of Trenton.
Following the victory at Trenton, Washington and his Continental Army staff proceeded to
Allentown, where they passed up Lehigh Street, then called Water Street, where they stopped at the foot of the street at a large spring on the property that is the present-day Wire Mill. There, Washington and staff rested and watered their horses, and then went their way to their post of duty.
20th century
In 1941, from
Cedar Crest Boulevard in
Emmaus to S. 6th Street and Auburn Street at present-day
PA Route 145 in
Allentown, Lehigh Street was designated as
Pennsylvania Route 29. In 1960, the designation was removed and it was called Lehigh Street.
Route description

Lehigh Street is a continuation of State Avenue near
South Mall in the northern sections of
Emmaus. After crossing the
Allentown border with Emmaus, it widens to a four-lane road with a center left-turn lane. From there, Lehigh Street runs northward traversing one of the busiest commercial districts in the city.
North of 29th Street SW, Lehigh Street interchanges the overlap of
Interstate 78 and
Pennsylvania Route 309, continuing through an underpass east of
Allentown Queen City Municipal Airport. The street runs away of the airport in its northward progression. At Lehigh Street's intersection with Jefferson Street, Lehigh Street narrows to two-lanes and turns slightly in a northeast course. North of 12th Street in Allentown, the street does not have the center left-turn lane.
A few blocks from South 12th Street, Lehigh Street intersects several Allentown-area roads and passes south of
Bicentennial Park, an outdoor athletic stadium At Wyoming Street, Lehigh turns east and widens to three-lanes with two southbound lanes and one northbound lane and continues west past South 8th Street and Allentown's
Albertus L. Meyers Bridge. It then heads eastbound as Saint John Street up to South 6th Street, also known as
PA Route 145.
Lehigh Street westbound splits at the intersection with
PA Route 145 at South 6th and Auburn Streets four blocks from
Center City Allentown. The one-way roadway merges with Saint John Street, which then becomes Lehigh Street eastbound. North of this, PA 145 follows two-way Lehigh Street north, intersecting with Martin Luther King, Jr. Drive. Lehigh Street ends at the intersection with Union Street in Center City Allentown, where PA 145 splits into a one-way pair along that street.
