Drove up to Durham at the weekend. Bluetooth tethered satnav to my phones web connection for traffic updates. as i set off it flagged up delays on the A174 at Middlesboro so kept an eye on it. 20 mins later the flag disappeared so carried on assuming the hold up had cleared.....1-3/4 miles from the A174/A19 junction it flagged again........100 yards from the back of the stationary traffic. no option to reroute on the dual carraigeway so had to sit in traffic. 30 minutes to go 1-3/4 bloody miles. Road filtered into one lane a mile before the junction and as some of you may know, that junction is an underpass roundabout.....with traffic lights. No sign of works until i got to the roundabout.......why do they need a lane closure so far from the works ?
