This <br />corridor is the Trunk Highway 10 diagonal. In order to meet the volume needs, all of the <br />at grade intersections should be removed along the Trunk Highway 10 diagonal. This has <br />been the Minnesota Department's ofTransportation position for the last decade and has <br />been supported by Metro District Traffic, the Regional Transportation Management <br />Center, as well as Area Management. This was the concept used to support the TeAAP <br />redevelopment plan. <br /> <br />Alternate scenarios that limit the capacity of the TH 10 diagonal (signalized intersections) <br />have been proposed and discussed with Minnesota Department of Transportation district <br />staff. Cursory analysis of this intersection requires significant increase in the right of way <br />of the 1-694 and 1-35W interchange area to accommodate the increase in diverted traffic <br />due to this proposed intersection on the TH 10 diagonal when the 1-694 and 1-35W <br />interchange is rebuilt. <br /> <br />Safety of the traveling public is the top priority of Minnesota Department of <br />Transportation. This intersection ranks in the top quartile of our Top 200 High Crash <br />Cost Intersections. That is why Minnesota Department of Transportation fully supports <br />Ramsey County and their project to grade separate the current TH 10 and CSAH 96 <br />intersection. By allowing a signalized intersection (temporary or permanent) to the north <br />of the current intersection, most of the current crash problems would also move north. <br />Spending millions of dollars to remove a signal system, then allow another signal system <br />to be installed would negate the benefits of increased safety and mobility of the Ramsey <br />County project. This would be a grave disservice to the traveling public. <br />
