Network and FLEX Piece Capabilities
Key
| Yes | This particular feature can be constructed, with minimal (if any) limitations. |
| Partial Support | This particular feature can be constructed, but not in all instances. Details will be given as to what is/is not possible. Partial support may be for intentional design reasons (such as realism or general unfeasibility), or simply because the feature has not been fully developed. |
| Limited Support | This particular feature can be constructed, but only in extremely limited circumstances. Instances that are possible may be listed, insofar as it is possible. Use at your own risk. |
| No Support | This particular feature cannot be constructed. This restriction could be for intentional design reasons (such as realism, general unfeasibility, or game limitations), or simply because it has not yet been developed. |
Additional Notes
OxO: OxO stands for “orthogonal x orthogonal”, and refers to a situation where both networks are orthogonal (in a straight line) along the game’s grid, intersecting perpendicularly (at 90° angles at all corners).
OxD: OxD stands for “orthogonal x diagonal”, and refers to a situation where the given network is orthogonal (in a straight line) along the game’s grid, and the cross network is diagonal (running at a 45° angle).
DxO: DxO stands for “diagonal x orthogonal”, and refers to a situation where the base network is diagonal (running at a 45° angle), and the cross network is orthogonal (in a straight line) along the game’s grid.
DxD: DxD stands for “diagonal x diagonal”, and refers to a situation where both networks are diagonal (running at a 45° angle) along the game’s grid, intersecting perpendicularly (at 90° angles at all corners).

FLEXRamp / Draggable Ramp Interfaces (DRI)
Orthogonal Mainline
Note that QuickChange support requires support for A1 ramps.
Diagonal Mainline
Fractional Angle Mainline
Not currently supported.
FLEXHeight Transitions
Orthogonal Ramp-Style Transitions
Orthogonal On-Slope Transitions
Diagonal Ramp-Style Transitions
Orthogonal On-Slope Transitions
FLEXWidth Transitions
Orthogonal Transitions
Note: S-to-C Transitions support asymmetrical combos, so additional possibilities exist beyond what is strictly indicated on this table, with the only limitation being that each network have the same number of lanes or differ by only one per side– i.e. RHW-6S (3 lanes per side) can transition to RHW-4 (2 lanes per side), RHW-6C (3 lanes per side), and RHW-8C (4 lanes per side).
Diagonal Transitions
Not currently supported.
Fractional Angle Transitions
Not currently supported.
FLEXFly Crossings
FLEXSPUI Crossings
Wide-Radius / Multi-Radius Curves
Fractional Angle Support
As Fractional Angle support for the RHW is entirely puzzle piece-based at present, see the listings in the Menu Items section, under the FARHW, FARHW Ramp Interfaces, and FARHW Intersections and Transitions buttons.
FLEX Turn Lane Intersection Support
Orthogonal x Orthogonal (OxO) Intersections
Bridges
Refer to the Bridges section of the RealHighway Mod feature guide for a list of bridge styles that are available.
All RHW networks, with the exception of the 6C and 8C networks, are capable of creating bridges.

| RHW-3 | RHW-2 |
| MIS Ramp | RHW-2 |
| RHW-4 (single) | RHW-2 |
| RHW-4 (dual) | GHWY |
| RHW-6S (single) | RHW-2 |

| RHW-8S | GHWY |
| RHW-10S | GHWY |
| RHW-6C | No support |
| RHW-8C | No support |
| DD RHW-4 | RHW-2 |
Tunnels
Due to the nature of the DirtRoad network, tunnels were never implemented and as such, are impossible to use in the game. However, there is currently some work being done on emulating tunnel functionality by using other networks with the FLEXFLUPs project.
Network ID Assignments
The RealHighway Mod uses the following ID ranges:
| Network Range | Purpose |
|---|---|
0x5700 - 0x57FF | Current RHW range |
0x7700 - 0x77FF | LHD Path remapping range |
Within the Network Addon Mod, the RealHighway Mod occupies the entire 0x57 range.
There are some Flex FARHW pieces in the 0x56F range, and there are also a handful of legacy RHW puzzle pieces in 0x5E.
