I am from Port Royal, and have traveled those roads for years. The Essex portion is almost always covered by police, but the stretch between Port Royal and Fredericksburg of 17 is two lane, and I have NEVER seen a cop checking speeders (i went to HS in Fredericksburg, traveled the road 2-4 times a day) and they hardly ever travel the road. That stretch of 17 is rural, and the people that know it are crazy. Now 301 between Port Royal and Bowling Green there is sometimes a cop at the top of the very first hill, but almost always right before the prison, and usually right after. The rest of the way is generally clear although occasionally you may find one, generally i don’t do more than 64 (its a 55) but they usually will pull an out of state person first. Between bowling green and I-95 I have seen a cop in just about every single crossover. Especially the one after the Kingdom Hall (going south), the second(?) one after the industrial park (going north). Basically the whole road is tough, just be careful, especially if you are from out of state.
