study should be low, however, improvements could get expensive and complicated if they require assistance or approval from adjacent property owners. B-1.4. Minor Arterials Rt. 94 from Rt. B to Rt. 370 is on the Illustrative list for improvement. Consideration should be given to widening the road from two to four or five lanes instead of just a three-lane road. Rt. N from I-64 to Rt. Z should be closely monitored to determine if the planned widening to three lanes will be sufficient. This area is experiencing substantial growth and it is expected to continue into the future. Although the forecasts do not indicate volumes in excess of capacity, they are quite marginal. Depending on how fast growth continues, the three lane road proposed may not be sufficient and a four or five lane facility may be needed. Rt. Z from I-70 to Rt. N is another road that should be monitored closely by MoDOT. Growth in this part of the county has been very high and could easily exceed forecasts. Should volumes increase over the ones predicted, the road will exceed its capacity and need to be widened to four or five lanes instead of just three. B-1.5. Major Collectors Rt. P is a road whose growth is unpredictable. Should development continue beyond expectations the road will need widening over what is presently considered by MoDOT. Traffic volumes should be closely monitored in future years. A number of rural MoDOT roads have poor safety records. Although specific ones have not been identified, the chapter on safety clearly pointed out that the severity rates on rural roads are normally higher than on suburban and urban ones. Traffic volumes should be carefully monitored as well as crash prone locations, those with poor horizontal and vertical alignment and limited sight distances. Proposed new entrances or side roads should be carefully checked to insure that they are not placed in locations that present additional hazards. B-1.6. Future MoDOT Funding Many of MoDOT’s projects described in this report can be expected to have reasonably high cost and probably will be beyond their present funding capability. This is based on state-wide and regional demands and priorities. Funds for new projects are quickly declining as a percent of total funds compared to funds that are needed to simply maintain the existing system. MoDOT has been examining ways of increasing present funding, but like many other DOTs and transportation authorities, they have found new sources hard to acquire. Future funds will not be able to keep up with future needs. Other means of funding transportation improvements may have to be considered in order to meet the ever increasing demand for road and street travel. B-2. County Roads B-2.1. Principal Arterials Most of the county’s principal arterial roads have been widened to four and five lanes. New traffic signals and other equipment have been installed to upgrade existing facilities. However, in many 124
cases traffic is continuing to increase and current controls are becoming inadequate. The county, with the help of the many municipalities, should continue to improve on its data collecting procedures. Current traffic volumes and crash data are needed to continually monitor the effectiveness of the system and assess future needs. This includes communication with and the efficiency uses of emergency vehicles. County roads that interface with MoDOT roads should be fully coordinated and integrated with theirs to reduce side effects from adjacent traffic problems. One major road that is going to need continued monitoring is Mid Rivers Mall Dr. between I-70 and Mexico Rd. This section of the road is presently operating with serious congestion during the peak hours and there is no room for expanding capacity. ITS type improvements are the only means of influencing and assisting traffic in this area. Because it is directly connected to I-70 and a potential growth area to the north, it will require special attention by county and municipal authorities. A major road that has ranked the top of the crash rating numbers is Mexico Rd. from Mid Rivers Mall Dr. to Rt. K. Because this road ranks every crash rating list, it deserves special attention. B-2.2. Minor Arterials As noted in chapter VI, most county minor arterials are operating with no serious problems. This could be an over simplification as so many parts of the county are growing and volumes are rising quite quickly. Close monitoring of future congestion and safety problems will have to be pursued by county and municipal authorities to insure that the roads continue to operate safely and efficiently. B-2.3. Major Collectors The county’s major collector roads are closely monitored by the County’s Transportation Department. They make decisions on how best to spend available funds for needed improvements. B-2.4. County Road Summary The St. Charles County Transportation Department and the public works department’s of all the municipalities are effectively using available funds designated for road and street improvements. Each agency has its own source of funding and additional funds are provided by the ½ cent Transportation Sales Tax, through a project selection process based on recommendations of the St. Charles County Road Board and approval of the County Executive and County Council. More major funding for road improvements come from federal funds. Projects are submitted to the Council for inclusion in the Council’s TIP and funds are provided from various federal funding categories through the current Federal Transportation Bill, SAFETEA-LU. This practice is expected to continue into the future. However, due to the fast pace of growth in the County, additional funds at all levels may be required to keep pace with the growing road improvement needs. C. Public Transportation Public transportation services that presently exist in the county are limited. As previously noted in Chapter III, future funds for fixed route transit or light rail transit are presently nonexistent due to the lack of a funding source in St. Charles County. This could change in future years depending on 125
