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
