5.7 Conclusions

5.7.1 All Options

All options would reduce the number of people living close to the route of the A14.However, all would also introduce traffic noise into rural areas and villages that arepresently considered to be largely free of traffic noise. At the same time, thereductions in noise to those houses close to the existing A14 may not beparticularly large and there will be some disbenefits to 1000 to 2,550 houses nearother roads in the network that would be affected by noise increases. There wouldbe decreases at between 15 and 320 houses, however, this would still mean a netincrease to 1,900 to 5,300 outside the area of any of the options. This is a muchgreater number than the 'net change from do minimum' summarised above for theaffects near the A14 and the route options.

EJS AND LJS OPTIONS

The EJS options show that the Blue - Orange followed by the Purple - Orangegive greatest benefits with the alternative A1 preferable in terms of noise. Theimproved environmental barriers help to improve the situation.

The Purple route shows the least benefit in terms of the EJS options with thealternative A1 junctions giving more benefits. However, there is little to choosebetween the two alternatives.

For the LJS routes, the Blue - Orange option with the alternative A1 junction isagain, the winner in terms of noise. These give slightly less benefit than the EJSroute options. The Blue route would give least benefits but again, the alternative A1junctions are the better choice with this option.

In terms of preventing noise increases, the Orange, Blue- Orange and Purple -Orange are better than the Purple or Blue Options.
