BYPASS HAS TO MIND THE LANDSCAPE
研究了奥克汉普顿绕行道路穿越达特穆尔国家公园的建设过程，强调通过谨慎选址、分幅设计和材料选择来减少环境干扰，对交通规划者和环保人士有参考价值。
Great tact, patience and sensitivity are required to ensure that the Okehampton bypass cutting across the Dartmoor national park is built with as little disruption and effect on the environment as possible. Constant liaison between statutory bodies and park authority is vital to give the public confidence in the way it is being built. The southern route was chosen after much debate, mainly because it would follow the hillside and be hidden from park visitors. Much of the proposed northern route would have covered valuable farmland and much of it would have been constructed on viaducts. The town would have also been sandwiched between moor and bypass, limiting the boundaries for any expansion. The route is of 8.5 km dual carriageway, with about 3.5 km being constructed as split level to reduce the landtake as well as help hide the road. Only flexible construction was considered since it was felt that blacktop was less noticeable than concrete. Footpaths disrupted by the construction are being reinstated with clear passageways. Local stone is used to face footings on one bridge, and another has its concrete columns of a reddish colour and a ribbed finish to blend with the surroundings. (TRRL)
