role as a regional artery. The Hawthorne Circle, where the Taconic, Saw Mill River Parkway and NY 100 intersected, was the major problem. It had become a magnet for accidents and congestion. A 1944 study recommended it be replaced with a three-level grade-separated interchange. The study also suggested eliminating some of the more dangerous grade intersections in Westchester as well. Without the money to build new exits, the TSPC settled for larger stop signs on the intersecting roads. It would seek the money for the interchanges after the war. The road's northern terminus had still not been settled. In 1942 state highway commissioner H.O. Schermerhorn suggested it might be more useful if the road veered west north of Chatham towards Albany to connect to a proposed bridge over the Hudson there. The TSPC inspected the proposed route and found it would be very expensive to acquire and build, and in 1943 Schermerhorn agreed that the Taconic should continue on its planned course northwards. Three years later, in 1946, the commission also considered the Hyde Park extension proposed by the recently deceased Roosevelt, but dropped it as construction was resuming with the end of the war. Paving had begun that year to Clinton Corners, but the commission became embroiled in controversy over Lake Taghkanic further north. In the two decades since the TSPC had bought the property, more cottages had been built along the lake. It would be necessary to condemn 110 of them to follow the proposed route west of the lake, similar to how the parkway had been built at Mohansic Lake to allow for a view from the road. The owners objected, and were able to persuade their state legislators to introduce a bill requiring a new parkway alignment at least west of the lake and prohibiting the commission from acquiring any property along it or constructing any of the road north of Route 199 until it had acquired a new route. Governor Thomas E. Dewey signed it into law in 1946 over Moses's objections, delaying planning for two years. Dewey also advocated the construction of a statewide "thruway" system of limited-access divided highways that would, unlike the parkways, be designed for buses and trucks as well as automobiles and serve commercial needs. Part of the system was a proposed "Berkshire Thruway" which would be the Taconic's northern terminus, even as the commission was studying a route through
