Deerpath/Route 41 Viaduct Project

From July 6 to on or about August 13, 2021, a new phase of storm sewer installation work will begin on Deerpath Road in Lake Forest. As a result of this work Deerpath will be reduced to one lane of traffic from the Rte. 41 viaduct to Ahwahnee Lane. Temporary traffic signals will be installed, to maintain east bound and west bound traffic via the one lane. Both the Rte. 41 south bound and north bound Deerpath exit ramps will be closed; the south bound and north bound entrance ramps will remain open. Suggested Rte. 41 exit ramp detours are Rte. 60 to the south and Rte. 176 to the north. Once access to Deerpath from Ahwahnee Road opens, access to Ahwahnee Lane will be closed.
