Weather permitting, during the week of October 3rd, PennDot will be milling and overlaying Norristown Road from Bethlehem Pike to just past McKean Road. The traffic signal loops will be cut and then restored when the paving is complete.

From the Lower Gweynedd Township Website:

the traffic signal loops will be cut and then restored when the paving is complete. You may notice an issue with the timing but that will be corrected at project completion.

Please plan accordingly.
