SOUTH WHITEHALL TWP., Pa. — The Tilghman Street exit from Route 309 — an intersection that averages more than 77,000 vehicles a day — will have new traffic patterns starting Monday.
The changes are for the $86 million continuing Route 309 and Tilghman Street interchange reconstruction project, the state Transportation Department District 5 announced.
Motorists should expect lane restrictions and possible traffic stoppages in the area from 3 p.m. Sunday through 6 a.m. Monday.State Transportation Department
Work to implement the new traffic patterns will begin Sunday afternoon, Sept. 7. Motorists should expect lane restrictions and possible traffic stoppages in the area from 3 p.m. Sunday through 6 a.m. Monday.
Starting Monday, Route 309 north access to Tilghman Street east and west will use the same ramp, PennDOT said in a release.
Access from Route 309 north to Tilghman Street west will be controlled with a traffic signal, and access from Route 309 north to Tilghman Street east will be a merge configuration.
That configuration will remain in effect permanently, the release said.
Tilghman Street east will be reduced from two lanes to a single lane from Hausman Road to Parkway Road, and left turns from Tilghman Street east and west to Parkway Road will be restricted.
Tilghman Street traffic wanting to access Parkway Road will be detoured on Springhouse Road.
Pattern in effect 'several months'
The pattern is anticipated to be in effect for several months, the release said.
Left turn movements from Tilghman Street east to Hausman Road also will be restricted. Tilghman Street east traffic wishing to access Hausman Road will be detoured on Broadway.
That pattern also is expected to be in effect for several months, PennDOT said.

The closure of the Route 309 south ramp to Tilghman Street east that went into effect on Aug. 19 will remain in place until about Sept. 1, 2026.
For the duration of the interchange project, motorists can expect lane restrictions on Tilghman Street from 40th Street to just west of Hausman Road.
Restrictions are anticipated between 9 a.m. and 3 p.m. and 6 p.m. and 6 a.m. weekdays and anytime on weekends.
Motorists are advised to expect changing traffic patterns and allow for extra time traveling through the area.
There will be future times when Broadway will be closed, and there may also be off-peak times when lanes may be restricted on PA 309, PennDOT said.
Advance notice will be provided whenever traffic patterns change, the release said.
What the project will do
The project includes the reconfiguration of Route 309 at Tilghman Street interchange to improve safety and mobility.
It will include two bridge replacements — at Route 309 over Tilghman Street and another at Route 309 over Broadway Street.
It also will include rehabilitation of the Route 309 culvert over Little Cedar Creek, roadway drainage improvements, road base repairs, paving, and sidewalks on Tilghman Street.
The project began last fall and is expected to be complete in March 2030.State Transportation Department
Two new traffic signals also will be installed at the end of the reconfigured Route 309 ramps to Tilghman Street that will be coordinated with existing signals at Hausman Road at Cetronia Road, Tilghman Street at Parkway Road, and Tilghman Street at 40th Street.
This year utility infrastructure work, drainage facility work and work to install electrical conduit and foundations for traffic signals will take place.
Other work planned this year includes interchange ramp work, erosion and sedimentation controls, embankment work, roadway work on Route 309 and Tilghman Street, barrier installation and constructing a cul-de-sac at Windsor Drive and Midland Road.
Allan Myers, LP of Worcester, Montgomery County, is the general contractor on the $86,475,455 project, which began last fall and is expected to be complete in March 2030.
Route 309 in the area has an average daily traffic volume of 57,372 vehicles, according to PennDOT. Tilghman Street in the area has an average daily traffic volume of 20,101 vehicles, PennDOT said.
