Bridlington is a seaside town and fishing port in East Yorkshire. It was originally two towns: the Old Town, about a mile inland, grew up around the medieval Augustinian priory, while Bridlington Quay was the fishing settlement and harbour. The two merged in the mid-19th C when the railway arrived and Brid (as it's often called) developed rapidly as a resort.
The usual approach is to follow M62 east to Howden (J37), then take A614. From the north, take A64 or A19 to York, then A166 east to meet A614 at Driffield. By any route, expect congestion on summer weekends.
