Take the train on the same line as above, and get off at ''Fulwell''. Walk south on Wellington Road, and then turn right onto Park Road. Follow this road as it joins the A312 for about 1.5 km in total. Just below the A316 bridge, which you will see ahead of you as you follow the A312, there is a roundabout. The first left turn on this roundabout is an on-ramp for the A316. There is a bus stop and a pedestrian crossing here, and traffic is going uphill, and so is quite slow. One user waited here for about 30 minutes with a sign saying "M3". However, other users (see hitchmap.com) reportedly had less luck and recommended rather trying the service station 300 meters west on the A316.
