Avenue at McKnight). If the traffic were designed to be posted with an urban speed of 45 mph, no consideration of the 4-lane option would be necessary unless traffic increased by a factor of 3X the present AADT. This is the educated choice for the taxpayer and the environment. Even under the inflated County AADT projection, the life of the proposed 4 lane divided highway would be 60% expended by the time 4 lanes could be of any benefit to maintaining high traffic on a fully signalized roadway. By building two lanes now, the future maintenance coats will be substantially reduced and the roadsalt and impervious surface runoff reduced by 50%. Washington County Public Works Department Proposal No.1—'Do nothing alternative" Due to the acceptance by the County to comply with the request of Oakdale, the existing 22 foot wide road was not improved as part of the recent work on CSAH 10. The improved portion now has a rural section with two 12 foot lanes and 8 foot paved shoulders for a total of 40 feet. Further the road, which is considered by the County to be a major transportation route, has been allowed to deteriorate to be one of the poorest roads in the State. Washington County Public Works Department Proposal No. 5--Four-lane reconstruction, shifted alignment This alternative includes the construction of a four -lane roadway on a shifted alignment. The alignment of the proposed eastbound roadway is proposed to be shifted approximately 20 feet to the north of the existing road into Lake Elmo with a raised concrete median separating the eastbound and westbound roadways. This design also includes construction of a guardrail in the shoulders in the section through Armstrong Lake. This proposal would leave 3/4 of a mile of CSAH 10 as underutilized and as out of character with the rest of the road as the 4-land divided stretch of TH-5 The existence of this over -built road is now being used as a primary justification for an
