US 206 comes to the modified Somerville Circle, where it meets US 202 and Route 28. At this modified traffic circle, US 206 and Route 28 run through it while US 202 passes over it with ramp access. US 206 forms a concurrency with US 202 at this point and the two routes continue north into Bridgewater Township, briefly entering Somerville. The road features an interchange with US 22 and heads north with the Bridgewater Commons shopping mall on the east side of the road and the Somerset Corporate Center on the west side of the road. An interchange with Commons Way provides access to both these places. Past Commons Way, the road passes under Garrettson Road and comes to an interchange with I-287 that also provides access to I-78. Past the I-287 interchange, US 202/206 continue north as a two-lane undivided road past suburban areas. The road crosses Chambers Brook into Bedminster Township, where it soon passes under I-78. Shortly after I-78, it widens into a four-lane divided highway with a Jersey barrier. US 202/206 come to another interchange with I-287, pass over the North Branch Raritan River, and come to an intersection where the two routes split.
