,The-iin ent 'e te ie th 0llfitml lt fi of highways more particularly designed for accommodating through traffic and is the object of the invention to obtain a construct ion which provides, an exclusive right; of way for the fast traiiic without interference either by cross trafiic or traflic entering or leaving the highway; p r

{ It is a further object to provide an exclusive right of way for 1 collective transportation -including rail and road vehicles. 7

Furtherobj'ects are to provide for s'ep;

amtion f e t m t tr fie f m le he l l' trailic with means forpassing from the one to the other; t'o 'p'rovide communication between the lanes for slow moving vehicles and the intersecting highways at one grade with an arrangement of the lanes fen-fast motor traffic and the rail traffic at a different non intersecting grade; to arrange rail stations at the elevated portions of the exclusive right of way where the opposite grades will {assist I in retarding the approaching cars and accelerating the departing cars; to v provid'e completely protected under crossings for pedestrians and throughwhich accessmay be Tobtain'edto the rail stations. With these and other objects in view the invention consists in the construction as hereinafter set forth.

Heretofore highways have been constructed with a separation of grade at points of intersection with cross highways or railways. Such constructions only partially solve the problem of safeguarding the traflic for it is necessary to provide inter-communication between the crossing highways with the consequent danger of collisions at such points of inter-communication. It is the primary object of the present invention to avoid such danger by a construction in which the fast moving traflic and slow moving traffic are in separate parallel lanes. This permits of uninterrupted traflic in the fast moving lane while the slow moving lane provides for communication with the crosscrossing highways, the track L ei hteen ne re emed now oftrees. brother means for lessening the densei' if-the h hte t nal P s e vehicle from one to the other. v N w At-gpoints ,of ihtersection between the h fldz is n edlehee De d D1 r h at-awhi e th h ereeet nsi hi h a s pte ehly. l ep h e a dee eerh A th me h' '.eiew e a n e the e eti ss wa there maybe arranged stations E for the ilW y ithe ehv t k e .a veh se, e the ri t l che k the me n m et a. e pi ear and edewh-e i he t i ii eel a e e ertins at;v .Fuitthet elf exi andh rhh ot the t ien m yb xjwey it W-h lh fnee the e e a t ek hh sh; iiee lanes, asi d ated woi t eiz e and p ra el e hei ieh s ed. an s. @FilQli ed lanes G, G" which are at the same gra e as the high speed lanes D, D excepting at intel-section points of the crossing highways.

Here the two lanes are separated the low speed lan declining downward to the grade of the crossing highway and providing inter-communication therewith. If desired, the high speed and low speed lanes may be separated by a grass plot or curbing cut away at frequent intervals for inter-communication between the two lanes.

With the construction described, the highways A may be used for the main thoroughfares and permit of high speed both for the rail traflic and the road trafiic. At the same time, low speed trafiic is accommodated and forms a .safe intermediateavenue for pas sage from the high speed lanes to the intersecting highways.

What we claim as our invention is:

1. A highway construction comprising separate lanes for high speed and low speed traffic having frequent points of inter-communication, said lanes being separated in grade at crossing highways with the low speed lanes at the grade of the cross highway.

2. A highway comprising separate parallel lanes for high speed and low speed traffic having frequent points of inter-communication, a cross highway at the grade of the low speed lane at the points of intersection therewith and said high speed lane being elevated to pass over said intersecting highway.

3. A highway comprising parallel high speed and low speed lanes having frequent points of inter-communication and at the same grade for the greater part of their extent, a crossing highway at a lower grade than said first mentioned highway, downwardly inclined portions of said low speed lanes forming inter-communication with said crossing highway at the grade thereof and upwardly inclined portions of said high speed lanes for passing uninterruptedly over said crossing highway.

4. A highway comprising parallelly arranged rail tracks and roadways on opposite sides thereof and separated therefrom, said roadways being divided into parallel lanes for the high speed and low speed traffic with the high speed lanes adjacent to said tracks, an intersecting highway having grade com munication with said low speed lanes, an elevated portion of said high speed lanes and tracks for separating the grade of the same from said intersecting highway, and a railway station at said elevated point.

5. A highway comprising parallelly arranged rail tracks and roadways on opposite sides thereof and separated therefrom, said roadways being divided into parallel lanes for the high speed and low speed traffic with the high speed lanes adjacent to said tracks, an intersecting highway having grade communication with said low speed lanes, an elevated portion of said high speed lanes and tracks for separating the grade of the same from said intersecting highway and a railway station atsaid elevated point and a tunnel communication with said station beneath said high speed lanes forming means of entrance and egress therefrom.

6. A highway comprising parallelly arranged rail tracks and roadways on opposite sides thereof and separated therefrom, said roadways being divided into parallel lanes for high speed and low speed traffic with the high speed lanes adjacent to said tracks, an intersecting highway having grade communication with said low speed lanes, an el rated portion of said high speed lanes and tracks for separating the grade of the same from said intersecting highway, a railway station at said elevated point, and means built into the supporting structure of said elevated portion providing communication between said railway station and the level of said intersecting highway.

7. A highway comprising high speed and low speed lanes having frequent points of inter-communication and at the same grade for a greater part of their extent, parallelly arranged rail tracks between said high speed lanes and separated therefrom a crossing highway at a lower grade than said first mentioned highway, downwardly inclined portions of said low speed lanes forming inter-communication with said crossing highway, and upwardly inclined portions of said high speed lanes and rail tracks for passing uninterruptedly over said crossing highway.
