Guidelines to Building Roads
Building Roads
The rules for building roads are either 1) Too Complicated, 2) Too Expensive or 3) Non-Existent. This is a very simplified way of treating road building, which includes materials and carriage in.
Road Building is a simple matter of picking a Style, a Width, and applying that to the distance (in miles).
Road Style
Style | Cost per Mile | Labourers required to construct 1 mile in 1 month | Special |
Dirt | 50gp | 12 | |
Hard Packed Dirt | 75gp | 24 | |
Gravel | 350gp | 16 | Providing gravel reduces the cost to 50gp |
Cobbled | 500gp | 48 | Providing rough stone reduces the cost to 100gp |
Paved | 750gp | 48 | Providing smooth stone reduces the cost to 200gp |
Shoon | 2,000gp | 160 | Providing Light & Coarse gravel, Rough Stone, and Smooth stone reduces the cost to 450gp |
Road Width
Width | Multiplier |
Single Carriage (5’) | 1x |
Dual Carriage (10’) | 2x |
Highway (15’) | 2.5x |
Building Bridges
Much like roads, building bridges is also overly complicated. These rules simplify the creation of bridges, like the roads above.
Bridge Style
Style | Cost per Foot | Labourers required to construct 20’ in 1 month | Special |
Wood | 75gp | 4 | Providing wood reduces the cost to 30gp |
Rough Stone | 200gp | 20 | Providing rough stone reduces the cost to 55gp |
Smooth Stone | 250gp | 20 | Providing smooth stone reduces the cost to 55gp |
Arched | +25gp | - | Making a bridge arched allows you to ignore depth & pylon stability – the length of a bridge is limited to the designer’s Knowledge (Engineering) x 2 |
Depth Below Bridge
Depth | Multiplier |
0-5’ | x1 |
6-15’ | x1.5 |
16-30’ | x2 |
31-50’ | x3 |
51-100’ | x5 |
101-200’ | x10 |
201+ | Impossible |
Pylon Stability
Ground is… | Multiplier |
Bed Rock | 1x |
Hard Packed Dirt or gravel | 1.5x |
Mud | 3x |
Bridge Width
Width | Multiplier |
Single Carriage (5’) | 1x |
Dual Carriage (10’) | 2.5x |
Highway (15’) | 3.5x |
Examples
Ex 1: 60’ rough stone single carriage bridge over a gravel river ford (average of 2’ deep)
60 × 200gp x 1 × 1.5 × 1 = 18,000gp
Ex 2: 60’ smooth stone double carriage bridge over a deep muddy river (average of 8’ deep)
60 × 250gp x 1.5 × 3 × 2.5 = 168,750gp
Ex 3: 60’ smooth stone arched double carriage bridge over a deep muddy river (average of 8’ deep)
60 × 275gp x 1 × 1 × 2.5 = 41,250gp
Ex 4: 30’ rough stone arched single carriage bridge over a deep chasm (over 300’ deep)
30 × 225gp x 1 × 1 × 2.5 = 16,875gp
