Morrison <br /> Clerk Administrator <br /> City of Arden Hills <br /> 1450 West Highway 96 <br /> Arden Hills, Minnesota 55112 <br /> Dear Ms. Morrison, <br /> SIJB.JECT: S.P. 6204 (TH 10) at T.H. 96 <br /> I am writing as a follow-up to your August 25, 1987 letter to <br /> Mr. Don Fashant and our recent phone conversation. <br /> Mn/DOT has a signal revision project presently scheduled for a March 1988 <br /> letting. That project will upgrade the traffic signals along T.H. 10 <br /> between Silver Lake Road and T.H. 96. <br /> The revisions will include adding double overhead indications (one signal <br /> . head above each of the thruugh lanes) and moving the vehicle detectors <br /> back further from the intersectione The double 'overheads will increase <br /> the signal visibility to approaching motorists and the extended detectors <br /> will reduce the likelyhood of the signal turning red when approaching <br /> traffic would have a hard time stopping. <br /> We are also considering building another left turn lane next to the <br /> one inplace for southbound T.H. 10 traffic turning to eastbound T.H. 96. <br /> It would then become a dual left turn movement which would reduce the <br /> number of times traffic in the turn lane would back up out into the <br /> through lanes. <br /> We think these improvements will be very beneficial and have a larger <br /> impact on traffic safety than would advance warning flashers. The <br /> flashers that we have on a few highways in the metro area have not <br /> produced a measurable reduction in accidents so there is no strong <br /> justification for their use at this time. They have been, however, <br /> very popular with motorists. <br /> At the present time we think it is advisable to proceed with the signal <br /> revisions that are planned. In the future, advance warning flashers <br /> could be considered if there appears to be justification. <br /> Please feel free to contact me if you have any questions about this <br /> matter. <br /> . ~;(~ <br /> Michae 1 L.
